VPU_VIU_VENC_MUX_CTRL

Configures the routing between VIU (Video Input Unit) and encoders. Each VIU

outputs data (image pixel component values) that feeds into encoders. Each

encoder outputs a Vsync signal that drives VIU operation. The data and Vsync

signals are configured together, with an exception that lets the hardware

ensure that the VIU blocks operate in sync.

SelfType & set_vsync_shared_by_viu_blocks (typename SelfType::ValueType val)

If true, the hardware ensures that the VIU blocks operate in sync.

The hardware keeps the VIU blocks in sync by routing the same Vsync signal

to them. Concretely, the Vsync signal from the encoder configured by

`viu2_encoder_selection` is also routed to VIU1, so Vsync routing ignores

`viu1_vsync_encoder_selection`.
