disp: msm: dsi: fix compressed RGB101010 support

Browse Source 
The destination format for compressed rgb101010 should be
the same as rgb888. After adding uncompressed RGB101010 support,
the programming for compressed rgb101010 went wrong.
Fix this to re-enable compressed rgb101010 format support.
