Make the necessary changes to the DP driver to use the qmp phy from the
common phy framework instead of rolling our own in the drm subsystem.
This also removes the PLL code and adds proper includes so things build.

add event thread to execute events serially from event queue. Also
timeout mode is supported which allow an event be deferred to be
executed at later time. Both link and phy compliant tests had been
done successfully.
Changes in v2:
-- Fix potential deadlock by removing redundant connect_mutex
-- Check and enable link clock during modeset
-- Drop unused code and fix function prototypes.
-- set sink power to normal operation state (D0) before DPCD read
Changes in v3:
-- push idle pattern at main link before timing generator off
-- add timeout handles for both connect and disconnect
Changes in v4:
-- add ST_SUSPEND_PENDING to handles suspend/modeset test operations
-- clear dp phy aux interrupt status when ERR_DPPHY_AUX error
-- send segment addr during edid read
-- clear bpp depth before MISC register write
Changes in v5:
-- add ST_SUSPENDED to fix crash at resume
Changes in v6:
-- at msm_dp_display_enable() do not return until resume_done to avoid
kms commit timeout

-- Add support of pm ops in display port driver
-- Clear bpp depth bits before writing to MISC register
-- Fix edid read
