Value for getting frequency capability wrongly has been taken from
register offset instead of register value.

In the commit be5ce0e97cc7 ("i2c: mediatek: Add i2c ac-timing adjust
support"), we miss setting OFFSET_EXT_CONF register if
i2c->dev_comp->timing_adjust is false, now add it back.

acpi_i2c_find_adapter_by_handle() calls bus_find_device() which takes a
reference on the adapter which is never released which will result in a
reference count leak and render the adapter unremovable.  Make sure to
put the adapter after creating the client in the same manner that we do
for OF.

Pull driver core updates from Greg KH:
 "Here is the big set of driver core patches for 5.15-rc1.

  These do change a number of different things across different
  subsystems, and because of that, there were 2 stable tags created that
  might have already come into your tree from different pulls that did
  the following

   - changed the bus remove callback to return void

   - sysfs iomem_get_mapping rework

  Other than those two things, there's only a few small things in here:

   - kernfs performance improvements for huge numbers of sysfs users at
     once

   - tiny api cleanups

   - other minor changes

  All of these have been in linux-next for a while with no reported
  problems, other than the before-mentioned merge issue"

The zynqmp platform now supports chip-off so the registers can
lose context.
Implement save restore for i2c module.
Since we have only a couple of registers
an unconditional restore is done.

Iff platform_get_irq() returns 0 for the main IRQ, the driver's probe()
method will return 0 early (as if the method's call was successful).
Let's consider IRQ0 valid for simplicity -- devm_request_irq() can always
override that decision...
