drm/amd/display: Fix CRC engine 1 enable/disable on DCN3.1.2+

[Why]
Multi-ROI CRC uses OTG_CRC1_EN for the second engine, but the driver
only toggled OTG_CRC_EN and cleared the whole OTG_CRC_CNTL register on
disable.

[How]
Program engine 1 via OTG_CRC1_EN where supported, disable each
engine independently by crc_eng_inst, and add the missing mask on
relevant DCN ASICs.
