drm/i915/dp: Helper to check for DDI BUF status to get active
Based on the platform, Bspec expects us to wait or poll with
timeout for DDI BUF IDLE bit to be set to 0 (non idle) or get active
after enabling DDI_BUF_CTL.
v2:
* Based on platform, fixed delay or poll (Ville)
* Use a helper to do this (Imre, Ville)
v3:
* Add a new function _active for DDI BUF CTL to be non idle (Ville)
v4:
* Use the timeout for GLK (Ville)
v5:
* Add bspec quote, change timeout to 500us (Ville)
