drm/i915/cx0: Update C10/C20 state calculation

Browse source

Update several functions in intel_cx0_phy.c to make PLL state
management more explicit.

Changes include
 * add 'const' qualifiers to intel_crtc_state parameter for
   cx0 state calculation functions
 * refactor C10/C20 PLL state calculations helpers to take
   explicit hardware state pointers instead of directly modifying
   'crtc_state->dpll_hw_state'
