Subject: [PATCH 01/18] media: venus: hfi_venus: Set
 venus_sys_idle_indicator to false on V6

This call does not seem to have been cast on any kernel with support
for VPU-1.0 or newer (and by extension, HFI6 and newer). Restrict it
to V4 only, as it seems to have been enabled by mistake and causes a
hang & reboot to EDL on at least one occasion with SM6115 / AR50L

Fixes: 7ed9e0b3393c ("media: venus: hfi, vdec: v6 Add IS_V6() to existing IS_V4() if locations")
Signed-off-by: Konrad Dybcio <konrad.dybcio@...aro.org>
