media: iris: Add support for HFI_PROP_OPB_ENABLE to control split mode

Browse Source 
Add handling for the HFI_PROP_OPB_ENABLE property, which allows enabling
or disabling split mode in the firmware. When HFI_PROP_OPB_ENABLE is set
to true, the firmware activates split mode for output picture buffers
(OPB). The OPB format is determined by the HFI_PROP_COLOR_FORMAT
property, supporting NV12 or QC08C formats.
