[Intel-gfx] [PATCH v4 01/20] drm/i915/icl: Define register for DSI PLL

[Madhav Chauhan]

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.
