These changes are required as the DSS2 driver since 3.3 kernel doesn't let you
set the overlay info with paddr as 0.

The data_type value to be programmed in the data descriptors to fetch/write a
UYVY buffer was not mentioned correctly in the older DRA7x documentation. This
caused VPE to fail with UYVY color formats.
Update the data_type value to fix functionality when UYVY format is used.

Also, make the default colorspace V4L2_COLORSPACE_SMPTE170M as that resembles
the Standard Definition colorspace more closely.
