The GPIOLIB symbol currently require that
ARCH_WANT_OPTIONAL_GPIOLIB or ARCH_REQUIRE_GPIOLIB is selected
to be selectable.
The ARCH_REQUIRE_GPIOLIB does only one thing: select GPIOLIB.
This is just confusing: architectures that want GPIOLIB should
be able to configure it in no matter what, and those who
require it should just select GPIOLIB.
It also creates problems for drivers that need to state
"select GPIOLIB" to get dependencies: those depend on the
selected architecture to select
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB first, and will cause
compile errors for the few archs that state neither.
These intermediary symbols need to go.
As a first step, remove the dependencies so that:
- ARCH_WANT_OPTIONAL_GPIOLIB becomes a noop (GPIOLIB will be
available for everyone) and
- "select ARCH_REQUIRE_GPIOLIB" can be replaced by just
"select GPIOLIB"
After this patch we can follow up with patches cleaning up the
architectures one-by one and eventually remove the
ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB symbols altogether.

All it really does is make it possible to set

The WM8994 GPIOs clearly have a dedicated open drain control
register. Implement support for controlling this from GPIO
descriptor tables or other hardware descriptions such as
device tree by implementing the .set_single_ended() callback.
Before this patch, lines requesting open drain will just be
switched to input mode by the framework, thus emulating open
drain. But the hardware can do the real thing, so let's
support that.
As part of this, rename the debugfs string for output mode
from "CMOS" to "push-pull" because it is the term used in
the framework to signify a tomem-pole CMOS output.

The vx855 driver clearly states it has three groups of lines:
GPI, GPO and GPIO. The GPO are assumedly push-pull. The GPIO
are implicit open drain, but if the GPIO subsystem ask for them
to be explicitly open drain (i.e. set the flag on a machine table
that we want open drain) it will currently misbehave: it will
switch the GPIOs to input mode (emulate open drain). Instead:
indicate in the .set_single_ended() callback that we support
open drain and open drain only.

The menz127 driver tries to support open drain by detecting it
at request time. However: without the new callbacks from the
gpiolib it is not really working: the core will still just emulate
the open drain mode by switching the line to an input.
By adding a hook into the new .set_single_ended() call rather than
trying to autodetect at request() time, proper open drain can be
supported.

If GPIO hog configuration failed while adding OF based
gpiochip() then return the error instead of ignoring it.
This helps of properly handling the gpio driver dependency.
When adding the gpio hog nodes for NVIDIA's Tegra210 platforms,
the gpio_hogd() fails with EPROBE_DEFER because pinctrl is not
ready at this time and gpio_request() for Tegra GPIO driver
returns error. The error was not causing the Tegra GPIO driver
to fail as the error was getting ignored.

This makes use of the new .set_single_ended() callback to
set the GPIO line as open drain/open source using hardware.
The TC3589x can do this by either disabling the N-MOS
transistor (open drain) or the P-MOS transistor (open source)
of the output driver stage, in the first case making the signal
drive actively low and high impedance as "high" and in the second
case actively high and high impedance, which is as close to native
open drain support as we come.

Some GPIO controllers has a special hardware bit we can flip
to support open drain / source. This means that on these hardwares
we do not need to emulate OD/OS by setting the line to input
instead of actively driving it high/low. Add an optional vtable
callback to the driver set_single_ended() so that driver can
implement this in hardware if they have it.
We may need a pinctrl_gpio_set_config() call at some point to
propagate this down to a backing pin control device on systems
with split GPIO/pin control.

The Kconfig for this driver is currently:
config GPIO_MB86S7X
bool "GPIO support for Fujitsu MB86S7x Platforms"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity, so that when reading the
driver there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

The Kconfig currently controlling compilation of this code is:
config GPIO_BCM_KONA
bool "Broadcom Kona GPIO"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
