From: "Srivatsa, Anusha" <anusha.srivatsa@xxxxxxxxx>
Add register defines and shifts that control the RC buffer threshold
between encoder and decoder for eDP/MIPI and DP cases.
The actual values are calculated usung a helper function.
This patch adds the shifts to registers where the value will
be written during atomic commit.
v2:
- Use _MMIO_PIPE() instead of _MMIO_(_PICK()) (Manasi)
- Combine shifts (Manasi)
