drm/i915/icl: Calculate DPLL params for DSI

This patch calculates various DPLL dividers and
parameters for DSI encoder and adjust AFE clock
for DSI. For DSI, 8x clock is AFE clock.

v2: Extend haswell_crtc_compute_clock() for Gen11 DSI

v3: Rebase

v4: use port clock instead of bitrate.

v5: Reabse and remove divide by 5

v6 by Jani:
- Fix indent (Madhav)
- Fix dpll state calc for EDP and DP MST
