Currently VF VSI are being reset twice during a PFR or greater. This is
causing reset, specifically resetting all VFs, to take too long. This is
causing various issues with VF drivers not being able to gracefully
handle the VF reset timeout. Fix this by refactoring how VF reset is
handled for the case mentioned previously and for the VFR/VFLR case.
The refactor was done by doing the following:
1. Removing the call to ice_vsi_rebuild_by_type for
ICE_VSI_VF VSI, which was causing the initial VSI rebuild.
2. Adding functions for pre/post VSI rebuild functions that can be called
in both the reset all VFs case and reset individual VF case.
3. Adding VSI rebuild functions that are specific for the reset all VFs
case and adding functions that are specific for the reset individual
VF case.
4. Calling the pre-rebuild function, then the specific VSI rebuild
function based on the reset type, and then calling the post-rebuild
function to handle VF resets.
This patch series makes some assumptions about how VSI are handling by
FW during reset:
1. During a PFR or greater all VSI in FW will be cleared.
2. During a VFR/VFLR the VSI rebuild responsibility is in the hands of
the PF software.
3. There is code in the ice_reset_all_vfs() case to amortize operations
if possible. This was left intact.
4. PF software should not be replaying VSI based filters that were added
other than host configured, PF software configured, or the VF's
default/LAA MAC. This is the VF drivers job after it has been reset.

1.The SSI clock of X1000 not like JZ4770 and JZ4780, they are not
directly derived from the output of SSIPLL, but from the clock
obtained by dividing the frequency by 2. "X1000_CLK_SSIPLL_DIV2"
is added for this purpose, and ensure that it initialized before
"X1000_CLK_SSIMUX" when initializing the clocks.
2.Clocks of LCD, OTG, EMC, EFUSE, OST, TCU, and gates of CPU, PCLK
are also added.
3.Use "CLK_OF_DECLARE_DRIVER" like the other CGU drivers.

The PLL of X1830 Soc from Ingenic has been greatly changed,
the bypass control is placed in another register, so now two
registers may needed to control the PLL. To this end, a new
"bypass_reg" was introduced. In addition, when calculating
rate, the PLL of X1830 introduced an extra 2x multiplier,
so a new "rate_multiplier" was introduced. And adjust the
code in jz47xx-cgu.c and x1000-cgu.c, make it to be
compatible with the new cgu code.

If register_netdev() fails, the driver will attempt to cleanup the
q_vectors and inadvertently trigger a kernel BUG due to a NULL pointer
dereference.
This occurs because cleaning up q_vectors attempts to call
netif_napi_del on napi_structs which were never initialized.
Resolve this by releasing the netdev in ice_cfg_netdev and setting
vsi->netdev to NULL. This ensures that after ice_cfg_netdev fails the
state is rewound to match as if ice_cfg_netdev was never called.

If ice_init_interrupt_scheme fails, ice_probe will jump to clearing up
the interrupts. This can lead to some static analysis tools such as the
compiler sanitizers complaining about double free problems.
Since ice_init_interrupt_scheme already unrolls internally on failure,
there is no need to call ice_clear_interrupt_scheme when it fails. Add
a new unroll label and use that instead.

In certain designs, it is possible to add a battery on a populated i2c
bus without an sbs compliant charger. In that case, the battery will
unnecessarily and sometimes undesirably master the bus trying to write
info in the charger.
It is observed in many occasion that these battery "broadcasts" are even
corrupting other ongoing master to slave communication. I.e. the
multi-master support in the battery is inadequate.
Thankfully, the CHARGER_MODE bit allows designers to disable that SBS
battery behaviour.
This needs to be done once when the battery is first seen on the bus.

The SBS battery implements SMBus block reads. Currently the
driver "emulates" this by doing an I2C byte read for the
length followed by an I2C block read. The I2C subsystem
actually provides a proper API for doing SMBus block reads,
which can and should be used instead. The current implementation
does not properly handle packet error checking (PEC).
This change requires, that I2C bus drivers support I2C_M_RECV_LEN
or directly provide the SMBus API to access device manufacturer
and model name.

There is no valid case for supporting duplicate pseudoflavor
registrations.
Currently the silent acceptance of such registrations is hiding a bug.
The rpcsec_gss_krb5 module registers 2 flavours but does not unregister
them, so if you load, unload, reload the module, it will happily
continue to use the old registration which now has pointers to the
memory were the module was originally loaded. This could lead to
unexpected results.
So disallow duplicate registrations.

To prevent DoS attack, memory for bitmap is allocated per vfio_dma

Bitmap is populated for already pinned pages when bitmap is allocated for
a vfio_dma with the smallest supported page size. Update bitmap from
