msm_fb: display: fix the hang issue caused by solidfill pipe

When mdp pipe solidfill mode is disabled, the staled pipe info is used
to update mdp pipe regs. This caused mdp hang. Since
mdp4_overlay_rgb_setup function already resets solidfill mode, this
patch removes any pipe register updates that are related to disabling
solidfill mode.

msm_fb: Set timeline threshold for command mode to 2

For command mode panel, timeline threshold is 1 and we return
commit ioctl on DMA_P interrupt. This causes fps to drop
since sometimes overlay is kickoff just after vsync interrupt
causing DMA_P wait time more than 1 vsync period. Hence, increase
timeline to 2 and return commit ioctl on vsync interrupt.

msm: display: command mode panel release fence

For command mode panel, release fence should be signaled after the buffer is
sent to the panel.  For performance consideration, allow one more commit to be
queued.  Keep the second kick off as short as enough.

msm: pm: Update spm retention sequence to support per core retention

On krait revision < 3, power driver is not using full spm sequence and
calling into trustzone as a part of executing krait retention.
Also krait retention is not supported on secondary cores.

krait pass3 is upgraded to use full spm sequence, hence add support
for per core retention and avoid calling into trustzone
while executing retention.

mako: Add power collapse debug counters support.

Add platform device for PC debug counters. These counter stores the
warmboot entry/exit counters for each core on a non-cacheable always
on IMEM memory. This is a useful feature during debug to understand if
the system has correctly warmbooted after a power collapse.

Usage for core0 debug counters:-
counters at address 0x2A03F664 represent no of times PC attempted.
counters at address 0x2A03F66C represent no of times PC failed.
counters at address 0x2A03F668 represent no of times warm boot happened.
no of PC attemps = PC failures + warm boot entries.

msm: spm: set vdd directly for current cpu

In cases where a cpu is setting vdd for itself we need not
call msm_spm_smp_set_vdd through smp_call_function_single.

Without this change when CPU calls for itself when interrupts
are disabled we get following warning

Support for display gamma control

Originally written by Paul Reioux (faux123)

Modified from his original implementation as follows:
* Remove kgamma_ctrl sysfs entry - it did absolutely nothing
* Alter the show() functions to output the checksum in the
first entry, in order to match the expected input of
the store() functions.  This should not break existing
applications
* Move store/show code to a common function
* Add limit checks from Mike Cain (motley)
* Added a kgamma_apply sysfs entry which will apply
  the current state when anything is stored to it,
  instead of waiting until the next time the LCD
  is power cycled
