Split out of bxt_ddi_pll_select() the logic that calculates the pll
dividers and dpll_hw_state into a new function that doesn't depend on
crtc state. This will be used for enabling the port pll when doing
upfront link training.
v2:
* Refactored code so that bxt_clk_div need not be exported (Durga)
v1:
* Rebased on top of intel_dpll_mgr.c (Durga)
* Initial version from Ander on top of intel_ddi.c
