media: venus: hfi_venus: Only consider sys_idle_indicator on V1

[ Upstream commit 6283e483 ]

As per information from Qualcomm [1], this property is not really
supported beyond msm8916 (HFI V1) and some newer HFI versions really
dislike receiving it, going as far as crashing the device.

Only consider toggling it (via the module option) on HFIV1.
While at it, get rid of the global static variable (which defaulted
to zero) which was never explicitly assigned to for V1.

Note: [1] is a reply to the actual message in question, as lore did not
properly receive some of the emails..
