drm/i915/dsb: Indexed register write function for DSB.
DSB can program large set of data through indexed register write (opcode 0x9) in one shot. DSB feature can be used for bulk register programming e.g. gamma lut programming, HDR meta data programming. v1: initial version. v2: simplified code by using ALIGN(). (Chris) v3: ascii table added as code comment. (Shashank) v4: cosmetic changes done. (Shashank) v5: reset ins_start_offset. (Jani) v6: update ins_start_offset in inel_dsb_reg_write.
