msm: vidc: Add support for different errors

When hardware is overloaded or when max number of clients are
reached in driver or firmware, hardware error is sent to video
client. This change is to replace hardware error with actual
errors.

msm: vidc: configure and set hier-p layers

Firmware requires the max number of hier-p layers
to be used during the encode session to be set
in load resources state. Without this change,
firmware will not enable hier-p encoding. Also
switch to using HFI_PROPERTY_CONFIG_VENC_HIER_P_ENH_LAYER
to set the number of hier-p layers.

msm: vidc: Expose extradata size to userspace

Previously, the extradata size was included within VENUS_BUFFER_SIZE
and callers (primarily in userspace) wouldn't know how much extra
padding was added to the buffer size. Exposing it allows userspace to
query directly instead of doing guesswork.

msm: vidc: Change in input buffer size calculation

Right now, input buffer size is calculated based on
maximum supported height and width returned from FW.
These values are not true representation as they are
calculated for rotation usecase. Driver needs to use
max MB supported from FW. This change fixes the same.

This patch re-works bus scaling and clk management to respond to

integrated with overall driver clk and bus management.

Furthermore, two functions are added to the low level crypto driver. Low
level crypto driver is informed to save and restored hardware context if
necessary across PM suspend/resume.

crypto: msm: Don't enable crypto clock in PM resume

If a PM suspend happens right after resume, crypto driver returns
-EBUSY, since reaper worker thread has not kicked in. The suspend
can only succeed after timer kicks in to disable crypto clock and
free bus.
The solution is as the following. Don't enable crypto
clock and allocate bus bandwidth when entering resume if
there is no outstanding crypto requests. The next crypto
operation will enable crypto clock then. Further more, this patch
shortens the reaper timer from 1 second to 200 ms.
