If the ssi or codec drivers are not loaded (for instance, because spi or i2c
bus drivers are not loaded), returning -EINVAL will for people to unload and
then reload the module to get sound working. Returning E_PROBE_DEFER will
mitigate this.

There is a typo in the filename (i2c mentioned instead of i2s).
However, this is a redundant piece of information. Delete it
altogether.

Since the Samsung platforms have moved to pinctrl for pin muxing and that
is handled in the core the old GPIO based muxing code can just be removed.
Something similar had been submitted by Thomas Abraham back in March but
a resubmission following review never happened.

Mostly the mxs system design uses saif0 mclk output as the clock source
of codec. Since the mclk is implemented as a general divider with the
saif clk as the parent clock, let's register the mclk as a basic
clk-divider to common clock framework. Then with it being a clock
provdier, clk_get() call in codec driver probe function will just work.

Commit 75096579c3 ("lib: devres: Introduce devm_ioremap_resource()")
introduced devm_ioremap_resource() and deprecated the use of
devm_request_and_ioremap().
devm_request_mem_region is called in devm_ioremap_resource(). Hence that
part can also be removed.
Since devm_ioremap_resource prints error message on failure, there is
no need to print an explicit warning message.

sffsdr machine support does not build since at least v2.6.36
(~3 years). There is little hope of it being fixed, so remove
the support.

This part of bias settings are essential for WM8962 to power up. Without it
"wm8962 0-001a: DC servo timed out" might be prompted due to power-up failure
that happens to FLL if being used.
The driver's also bringing the bias down in the suspend path so it needs to be
powered up in the resume path for symmetry.
According to dapm_pre_sequence_async(), DAPM would call pm_runtime_get_sync()
to let driver finish the bias settings in pm_runtime_resume() before the bias
level being set to STANDBY. So no need to worry about disordered settings for
VMID of WM8962.
