drm/i915/bxt: Add HW state verification for DDI PHY and CDCLK
I caught a few errors in our current PHY/CDCLK programming by sanity
checking the actual programmed state, so I thought it would be also
useful for the future. In addition to verifying the state after
programming it also verify it after exiting DC5, to make sure DMC
restored/kept intact everything related.
v2:
- Inlining __phy_reg_verify_state() doesn't make sense and also
incorrect, so don't do it (PW/CI gcc)
v3:
- Rebase on latest -nightly
