Selective update area is now aligned with DSC slice height when
DSC is enabled. Remove inappropriate warning about missing DSC
alignment.

It is necessary check if DSC alignment and PSR2 alignment matches, if not PSR2 can't be enabled.

This check is there at the begin of
intel_psr2_sel_fetch_pipe_alignment:

/* ADLP aligns the SU region to vdsc slice height in case dsc is
enabled */
if (crtc_state->dsc.compression_enable &&
	(IS_ALDERLAKE_P(dev_priv) || DISPLAY_VER(dev_priv) >= 14))
		y_alignment = vdsc_cfg->slice_height;

For some reason when this got merged warning was still left there. Now
just removing the warning as well.

This is still wrong.
There is no guarantee that required PSR2 alignment matches vdsc_cfg->slice_height.

Thank you for pointing this out. Please check "DSC slice/PSR2 SU panel
y granularity alignment" patch set.
