Fix the following issues found in static analysis:
- missing blank lines after declarations
- unnecessary return in a void function
- exporting world writable files is usually an error
- block comments use * on subsequent and trailing lines
- Add DT binding description and vendor prefixe for the
driver.
- Add Linux Foundation copyright markings.

Before going for full PLL enable sequence, we need to clear out the
override bit and precalibrated values of VCO_TUNE and KVCO_CODE, as
these registers might be storing values for old VCO rate. This will
cause the DSI PLL to be in a bad state and hence PLL unlock errors
might occur during use case like resolution switch. So always clear
the precalibrated values first in PLL configuration sequence.

Currently mtp function driver is skipping function
setup call back by not populating function pointer
in function instance. Also, is_ptp flag is set
incorrectly as true for mtp instance which would
pass wrong os descriptor for mtp and ptp instance.
Allow mtp driver to send os descriptor by populating
function pointer in function instance and correctly
set the is_ptp flag to pass valid os descriptors.

Consider recent history (residencies) of the low power modes per
core while the next low power mode to enter is selected. If most
of the history says the pattern of residencies is repeating with
minimal deviation then use the average of these for predicting
the next mode to enter.
If the pattern is not repeating then if more than 50 percent of
the samples out of history have exited a low power mode earlier
than the minumim residency of that mode, restrict it and also low
power modes deeper than that.
In any of the above case, trigger a hrtimer to wakeup cpu with
timeout as predicted+delta or max residency of the mode selected
if a deeper state can be selected after waking up incase if
prediction goes wrong.
