drm/amdgpu: Use correct mask in dce_v8_0_afmt_setmode() and fix comment typos.

We were using the same mask twice. Looking at radeon, it seems
we should be using HDMI_AVI_INFO_CONT instead as the second mask.

Being there, fix typos in comments and improved readability.

I haven't looked at other DCEs, the mask may also be wrong for them.
