Subject: drm/i915/icl: Define register for DSI PLL
Git-commit: 27efd2566cb89b7909366dbb88add8fb1e3d24e2
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
This patch adds the new registers and corresponding bit definitions
which will be used for programming/enable DSI PLL.
v2: Review comments from Jani N
- Fix spaces while defining ICL_ESC_CLK_DIV_MASK
- Define shift and mask for bitfields.
