MMC bus suspend/resume was using legacy method. In system entering
S3 patch, the suspend/resume function cannot be called since MMC
bus also implemented the new suspend/resume method (dev_pm_ops struct).
So if dev_pm_ops is defined but .suspend/.resume callbacks not implemented,
mmc_queue will not be suspended/resumed.
This patch will remove the legacy suspend/resume method and change to
use the new method totally.

WCD9310 has four micbiases and each of them can be programmed to get its
power source from one of 3 available cfilters. Each cfilter can be
programmed to different voltage levels. Essentially, on WCD9310, a user
can have up to three different voltage levels to power various analog
microphones and digital microphones. As it is now, micbias voltage level
of WCD9310 is left to default value. Micbias and cfilter mapping is managed
by codec driver. Different board design can have different micbias
arrangement. Micbias configuration of wcd9310 CODEC for 8960 CDP/MTP/FLUID
is properly defined in this patch.

These two new APIs allow a driver to specify its PWM period
and duty cycle separately using PM8058 chip specific parameters

PWM register.

Slimbus can run in clock gears 1 through 10 per spec. Scheduling
algorithm tries to find the optimum clock gear depending on bandwidth
usage for messaging and active data channels.
However, not all controllers may have the ability to support all the

algorithm will only run the bus in supported slimbus clock gear.
Controllers can specify supported minimum and maximum clock gear
