radeon_hd: Fix DisplayPort link training

* Original changes by Bill Randle
* Includes a large number of modifications
and cleanups.
* Add a "currentMode" to the gDisplay to
enable easier checking of intended changes.
(we pass the display_mode around quite a
bit, adding a "currentMode" allows code
to know the intended display mode being set
without passing the mode pointer around as
much)

radeon_hd: Implement preferred mode

* Add preferredMode display mode to each display.
* If LVDS is detected, set preferredMode based on AtomBIOS
* Fixes blocker #8329 ?

Pointer style cleanup; Variable consolidation

Include file style cleanup, no functional change

Clean up engine and hooks

* clean up radeon_hd engine tracing
* clean up radeon_hd engine
* clean up radeon_hd hooks
* add engine accelerant count function

* add *very* preliminary dpms support
we will need to query the card dpms state
for each monitor at a later date

* add digital encoder setup code
* make encoder setup functions return status_t
* really need a struct to hold encoder info

* add encoder code to handle setting up and adjusting encoders
* reorganize mode set code to match layout of linux DRM driver
* add initial DPMS code
* add lots of TODOs

* Pass device name into shared info
* Refactor MCFBsetup to be a little simpler for now
* Implement radeon accelerant_device_info for screen preflet
* Re-add CRT Power calls to display code.
* Disable blanking setting for now... just can't figure out
what AMD wants for this.
* Remove some un-needed locking in the scaling code
* Be sure to disable VGA when set_display_mode is called
* Refactor mode setting code to loop over all possible displays
and set the provided mode on the attached ones.

add hook to pass EDID back if requested by userspace (screen applet); fix calculation of H blankStart; correct typo on H_SYNC vs V_SYNC register; set +/- V_SYNC to 0x01 vs 0x02.. this prob still needs work; style corrections

Work in progress of a Radeon HD 3200 driver to change the display mode (status when I leave the coding spring). At least it shows a picture but with a wrong scaling.
