disp: msm: sde: remove sde_hw_blk

The sde_hw_blk was meant to be a generic base object for all
SDE HW blocks, however, it enforces using a common set of ops
which is not practical when blocks have different capabilities.
Since this object was never used as intended and is not doing
anything functional today, remove the dead weight.
