msm: mdss: always get the rotator destination format



Rotator destination format can be different depending
in the source format. Previously we were only checking
the destination format for bwc or rot90, but this is
wrong since there are other scenarios like rotator
downscaling, where we need to get the destination
pixel format, otherwise we get some misconfiguration
and corruption is observed. This change makes sure
that always we get the expected destination format
for the rotator.
