dolby: fix 5008 crc error [1/1]

PD#SWPL-10487

Problem:
1.tb39 new case 5008, dm version is 3,
core3 raw_metadata overflow
2.core3 raw_metadata 207 overwrite core3 clkgate_ctrl
and core3 swap_ctrl0 andsawp_ctrl1 reg.

Solution:
1.Increase raw_metadata size to 512
2.Force dv_mode to DOLBY_VISION_OUTPUT_MODE_IPT, output
ipt444 12bit for 5008.
3.Dont set core3 metadata reg when scramble disabled or
metedata size > 204

Verify:
