This patch implements SKL DPLL programming that includes:
- DPLL allocation
- wide range PLL calculation and programming
- DP link rate programming
- DDI to DPLL mapping
v2: Incorporated following changes
- Added vfunc for function required outside
- Fixed multiple comments in WRPLL calculation
v3: - Fix the DCO computation
- Move the initialization up to not clobber the computed values
- Use the correct macro for DP link rate programming.
- Use wait_for() to wait for the PLL locked bit
v4: Rebase on top of nigthly (Damien)
v5: A few code cleanups in the WRPLL computation (Damien)
- Use uint32_t when possible
- Use abs_diff() in the WRPLL computation
- Make the 64bits divisions use div64_u64()
- Fix typo in dco_central_feq_deviation (freq)
- Replace the chain of breaks with a goto
v6: Port of the patch to work on top of the shared DPLLs (Damien)
v7: Don't try to handle eDP in ddi_pll_select() (Damien)
v8: Modified as per review comments from Paulo (Satheesh)
v9: Rebase on top of Ander's clock computation staging work for atomic (Damien)
