[PATCH v5 4/7] media: venus: hfi: Skip AON register programming for V6 1pipe

[Stanimir Varbanov]

From: Dikshita Agarwal <dikshita@xxxxxxxxxxxxxx>

AON register programming is used to set NOC to low power mode
during V6 power off sequence. However AON register memory map
is not applicable to 1pipe, hence skipping AON register programming.
