Currently driver is enabling hsphy_irq and ssphy_irq at the end
of dwc3_msm_suspend() without any spinlock/mutex protection. But
if it happens that hsphy_irq or ssphy_irq gets fired right after
enablement of irqs, there is a chance that we might see warnings
related to unbalanced irq enable. This could happen due to flag
is not yet set to indicate phy irqs enabled in suspend(). This
might cause phy irq left enabled after resume and could cause
crash due to unclocked access in host mode. Fix the unbalance irq
enable by having mutex protection and also extend mutex protection
for dwc3_msm_suspend() and dwc3_msm_resume().

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.
