disp: msm: sde: Add support for SB LUTDMA

Forráskód böngészése 
A new LUTDMA HW instance has been added to support programming of
SB features via LUTDMA. This change adds corresponding support for
the new SB LUTDMA, including catalog parsing, reg_dma init/deinit/ops
updates and new opcode support.
