Both struct dpu_dsc_sub_blks instances declare enc subblock length to be
0x100, while the actual length is 0x9c (last register having offset 0x98).
Reduce subblock length to remove the empty register space from being
dumped.

For the time being only ctl register 0x00 and 0x04 is touched,
DATA_IN_SWAP and CLK_CTRL at 0x08 and 0x0c are defined but not used,
though it might still be useful to see their current value in the dump.

Yes, we should keep them.
