This change adds a check for the length of the buffer
before copying it to avoid a buffer overflow.

Limit clock rate of shadow VCO clock as normal VCO clock.
For larger bit clock rate gap between switched ones, the clock switching
would fail due to mismatched VCO clock rate between normal VCO clock and
shadow one.

CRTC client type is wrongly identified as RT_CLIENT
for WB as the API considers only RT and RT_RSC. Resolve
it by adding a new API to check for RT CTRC.

Input handler is used for early wakeup DSI and MDP clocks from
idle power collapse. DSI clock won't be disabled in video mode
during idle power collapse, so the input hanlder isn't needed
for video mode.
This change avoids the input handler to be registered in
video mode.

Helper function is returning the width of single mixer. During
atomic crtc check, the number of destination scaler is not
considered before width check and can fail possible higher
resolutions. The mixerwidth should be taken as a multiple of
num_ds_enabled.

Update the minimum encryption level only when there is a request
to do so coming from the DRM framework. This will ensure that any
previously set value will not be overwritten while processing
other commands. Failure to preserve the minimum encryption level
can result in secure content playback failure if the sink device
is not updated with the correct value.

Break the host initialization and de-initialization to
create late initialization and early de-initialization.
Call host init/deinit on physical connect/disconnect only
As attention messages from sink doesn't change the physical
cable configurations, call only late init/early deinit in
this case to avoid unnecessary hardware resources
re-initialization.
