msm: sde: add format enumeration based on rotator version

Current pixel format enumeration reports pixel format supported
by driver, and may include formats not supported by underlying
hardware.  This patch reorganizes pixel format enumeration to
report hardware supported pixel formats based on hardware version
as well I/O port direction.
