Currently the code only waits 100mS between steps. The hardware
could take longer to deglitch its signals and status. Extend the
wait to 500mS.

mmc_blk_cmdq_part_switch always returned 0 even in case of
failures as errors are not handled in this function.
We need to un-halt cmdq in case it's in halt state when
mmc_switch fails. This change adds error handling code and
returns error in case of any failure.

Switching HDMI display mode many times, could find
sometimes color distortion or no signal display.
If disable HDMI block before setting HDMI core off,
that could be fixed.

composite driver is using sprintf() function to expose value to
userspace. This sprintf() is banned function and instead required
to use snprintf() function. Hence replace sprintf() with snprintf()
function to fix static analysis tool error.

Initial ISPIF waiting was one second which causes
hang for one second in case of sensor removal hence

SDHC core with 14lpp tech DLL should not enable PWRSAVE_DLL since
such controller's internal gating cannot meet following MCLK requirement:
when MCLK is gated OFF, it is not gated for less than 0.5us and MCLK must
be switched on for at-least 1us before DATA starts coming.
Since all the latest versions of sdhc host has this 14lpp tech DLL
Don't set PWRSAVE_DLL bit accordingly.
