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)

DisplayPort call organization and cleanup

* Add color space to BPP function
* Pass display_mode to DP lane count function
* Get BPP in DP lane count
* Move some DPInfo population out of DP link training
as other things need them sooner.
* Fill out DP code in external encoder setup

Pointer style cleanup; Variable consolidation

* fix TODO style due to ML
* rename bpc to bitsPerChannel
* remove un-needed / unused PCI BAR reference
* no functional change

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

* 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

* consolidate and remove unneeded Xorg headers
* move mc code to more generic gpu source/header
* add gpu reset functions (with r600 documented)

* Large refactoring of display detection and storage
* Create new display.c/h for display management
* Rename global gCRT to gDisplay
* Add CRT connection type into gDisplay
* Add CRT connection index into gDisplay
* Refactor registers for each display into gDisplay via regs
* We now shouldn't freak out too badly on multi-monitors


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42462 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Add mc.cpp for memory controller functions
* Remove read32MC as it doesn't apply to radeon cards >= r600
* Add tmds.cpp for tmds connected monitor management (current radeons
only have TMDSA for the moment) still needs TDMSPower, etc.
* Add some MC calls to mode.cpp, causes KDL so commented out atm.
* Add command to idle all DACs (although POWER_RESET doesn't do
anything on DACs, we should be consistent)

* Final (hopefully?) calculation for blank start/end
* Lets actually call PLLPower after PLLSet
* Improve screen blanking function
* Detect DAC/PLL to use separately from CRT id
* Add DACSense that senses displays on DACA/DACB
* Grab CRT in PLL code via gRegister crtid
* Set overscan to 0 for now
* Setting extended video modes now kinda works sometimes :-/

* malloc an array of pointers to hold active crt info, mode, limits, etc.
Plan to move gRegister into the crt struct at some point.
* Few style fixes
* Added function to probe edid of attached monitors and populate CRT info
* Disable VGA control modifications temporarly while I hammer out some issues.
* Fix radeon card model checks (bitwise & is not |)
* Finally fix? blanking start / end calculations using porch
* Use mask for setting sync polarity
* Add overscan (8 pixels is default?)
* Disable PLLSet/Power for the moment as it seems to muck things up.
* is_mode_supported now validates if a mode line is with the monitors
h/v sync frequencies (how does is_mode_supported know what crt the os wants?)
* PLL Write/Read don't actually use the PLL Write/Read functions (thanks AMD!)
* Added better PLL legacy (r600-r610) support
* Consistantly give no DCCG on legacy cards.
* Tracing!

* rename DxMode* to CardMode*
* make adjustments and implement radeon hd mode setting further
