drm/amd/display: Fix off by one in hdmi_14_process_transaction()
The hdcp_i2c_offsets[] array did not have an entry for
HDCP_MESSAGE_ID_WRITE_CONTENT_STREAM_TYPE so it led to an off by one
read overflow. I added an entry and copied the 0x0 value for the offset
from similar code in drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c.
I also declared several of these arrays as having HDCP_MESSAGE_ID_MAX
entries. This doesn't change the code, but it's just a belt and
suspenders approach to try future proof the code.
Fixes: 4c283fdac08a ("drm/amd/display: Add HDCP module")
