Width and height are not properly calculated when decimation
is involved. When there is scaling on a pipe, the required number
of pixels are wrongly programmed resulting in pipe hangs and
leading to TLB SYNC issues. This change handles proper
calculation of decimated width and height.

EDID (Extended Display Identification Data) may contain some
resolutions in DTDs (Detailed Timing Descriptors) which are not
in the supported resolutions list. In such cases, every time
when the HDMI cable is connected, parse all the resolution data
from DTD and populate the resolution list with the newly found
resolution. This way any resolution found in DTD can be supported
subjected to hardware limitations.

Provide complete resolution details in a sysfs node "res_info"

resolution details based on the resolution ids received from
EDID of the TV.
In case resolution details exceed PAGE_SIZE, reuse res_info to

HDMI has a large number of resolutions supported and currently
for all supported resolutions, related modules maintain static
tables which are populated at boot time. This results in huge
static memory usage. Also, it limits the system to support only
the define resolutions.
Remove static table which stores all the resolution details.
Get individual resolution details on need basis. Also, remove
the dependency to support only the defined resolution. HDMI driver
can support any non standard resolution within the allowed range.

Add support for enabling scrambler on hosts that support scrambling.
Scrambling is a new freature added in HDMI 2.0 specification to reduce
EMI interference at higher clock frequencies. Scrambling is enabled for
HDMI modes that have pixel clock greater than 340MHz. For lower pixel
clock frequencies, scrambling is enabled if sink supports scrambling at
lower frequencies.

Some of the PP(post processing) features in MDP might be upgraded when
new revision hardware is released. Clients of driver were relying on
MDP revision to decide which version of the PP feature is supported.
With MDP revision approach the client of driver needs to maintain a
mapping between MDP revision and PP feature version. This change
exposes ioctl to driver clients to query PP driver version of feature
instead of maintaining mapping.
