msm: rotator: Add proper checks for enabling Fast YUV

For rotator version 2.0 and above, there is support for fast
YUV which gives better rotator performance. However, there are
few constraints related to height under which fast YUV cannot be
enabled when 90 degree rotation is enabled. Make sure
to add proper checks before enabling fast YUV.
