drm/i915/bxt: Enable BXT DSI PLL
This patch adds new functions for BXT clock and PLL programming.
They are:
1. configure_dsi_pll for BXT.
This function does the basic math and generates the divider ratio
based on requested pixclock, and program clock registers.
2. enable_dsi_pll function.
This function programs the calculated clock values on the PLL.
3. intel_enable_dsi_pll
Wrapper function to use same code for multiple platforms. It checks the
platform and calls appropriate core pll enable function.
v2: Fixed Jani's review comments. Macros are adjusted as per convention.
v3: Removed a redundant change wrt code comment.
