disp: msm: sde: add rotation support with writeback block

Browse Source 
MDSS 10.0.0 HW is capable to rotate input image in WB hardware
block. WB hardware can only perform rotation of clockwise 90 degrees
and this can be used to achieve the required 2D rotation by adding
appropriate FLIP transformation to the SSPP. This change adds required
software support in display driver to excericse input image
rotation through WB block.
