Remove the old PHY ops managed by hdmi_platform_config and use them as ops
provided by the HDMI PHY driver.
Remove the old HDMI 8960 PLL code that used the top level HDMI TX mmio
base.
NOTE: With this commit, HDMI functionality will break until the HDMI
PHY/PLL register offsets in hdmi.xml.h aren't updated to be used as
separate domains.

Make HDMI core get its PHY by parsing the "phys" phandle. The core will use
this PHY reference to enable/disable PHY. The driver defers probe until PHY
isn't available.
The DT bindings used here is the same as the one used for PHYs using the
common PHY framework bindings.

Add a helper to initialize PLL in the PHY driver. HDMI PLLs are going to
have their own mmio base different from that of PHY.
For the clock code in hdmi_phy_8960.c, some changes were needed for it to
work with the updated register offsets. Create a copy of the updated clock
code in hdmi_pll_8960.c, instead of rewriting it in hdmi_phy_8960.c
itself. This removes the need to place CONFIG_COMMON_CLOCK checks all
around, makes the code more legible, and also removes some old checkpatch
warnings with the original code.
The older hdmi pll clock ops in hdmi_phy_8960.c will be removed later. The
driver will use these until the HDMI PHY/PLL register offsets aren't
considered as separate domains (i.e. their offsets start from 0).

Create a PHY device that represents the TX PHY and PLL parts of the HDMI
block.
This makes management of PHY specific resources (regulators and clocks)
much easier, and makes the PHY and PLL usable independently. It also
simplifies the core HDMI driver, which currently assigns phy ops among
many other things.
The PHY driver implementation done here is very similar to the PHY driver
we already have for DSI.
Keep the old hdmi_phy_funcs ops for now. The driver will use these until
the HDMI PHY/PLL register offsets aren't considered as separate
domains (i.e. their offsets start from 0).
The driver doesn't use the common PHY framework for now. This is because
it's hard to map our ops with the ops provided by the framework. The
bindings used for this is the generic phy bindings. So, this can be
adapted to the PHY framework in the future, if possible.

Some platforms may not have a HPD gpio line to detect Hot Plug signal from
the connector. They need to rely only on reading REG_HDMI_HPD_INT_STATUS
for HPD.
Modify hdmi_connector_detect logic such that it checks for HPD only using
the status register if there is no HPD gpio.

Make gpio allocation and usage iterative by parsing the gpios on a given
platform from a list. This gives us flexibility over what all gpios exist
for a platform, whether they are input or output, and what value they
should be set to.
In particular, this will make HDMI on 8x96 platforms easier to integrate
with the driver, as it doesn't have a HPD gpio input to them. Also, it
cleans things up a bit.
We still use the legacy gpio api here, as we might need to backport this
driver to downstream kernels.

amdgpu must load only after amdkfd's loading has been completed. If that
is not enforced, then amdgpu's call into amdkfd's functions will cause a
kernel BUG.
When amdgpu and amdkfd are built as kernel modules, that rule is enforced
by the kernel's modules loading mechanism. When amdgpu and amdkfd are
built inside the kernel image, that rule is enforced by ordering in the
drm Makefile (amdkfd before amdgpu).
Instead of using drm Makefile ordering, we can now use deferred loading
as amdkfd now returns -EPROBE_DEFER in kgd2kfd_init() when it is not yet
loaded.
This patch defers amdgpu loading by propagating -EPROBE_DEFER to the
kernel's drivers loading infrastructure. That will put amdgpu into the
pending drivers list (see description in dd.c). Once amdkfd is loaded,
a call to kgd2kfd_init() will return successfully and amdgpu will be able
to load.

Current dependencies between amdkfd and radeon/amdgpu force the loading
of amdkfd _before_ radeon and/or amdgpu are loaded. When all these kernel
drivers are built as modules, this ordering is enforced by the kernel
built-in mechanism of loading dependent modules.
However, there is no such mechanism in case where all these drivers are
compiled inside the kernel image (not as modules). The current way to
enforce loading of amdkfd before radeon/amdgpu, is to put amdkfd before
radeon/amdgpu in the drm Makefile, but that method is way too fragile.
In addition, there is no kernel mechanism to check whether a kernel
driver that is built inside the kernel image, has already been loaded.
To solve this, this patch adds to kfd_module.c a new static variable,
amdkfd_init_completed, that is set to 1 only when amdkfd's
module initialization function has been completed (successfully).
kgd2kfd_init(), which is the initialization function of the
kgd-->kfd interface, and which is the first function in amdkfd called by
radeon/amdgpu, will return successfully only if amdkfd_init_completed is
equal 1.
If amdkfd_init_completed is not equal to 1, kgd2kfd_init() will
return -EPROBE_DEFER to signal radeon/amdgpu they need to defer
their loading until amdkfd is loaded.
