[PATCH v2 13/18] media: venus: firmware: Correct IS_V6() checks

[Konrad Dybcio]

Most of these checks should have checked for TZ presence (or well,
absence), as we shouldn't really be doing things that the black box
does for us on non-CrOS platforms.

The IS_V6() check in venus_shutdown_no_tz() should have checked
whether the core version is IRIS2_1 (so, SC7280). Fix that.

Fixes: afeae6ef0780 ("media: venus: firmware: enable no tz fw loading for sc7280")
