Only two drivers were not in this table (7505 and g33), both non-mobile
chipsets. So they were most likely just missing. This is another step
to untangle the gtt from the agp driver.

intel-agp.c contains actually two different drivers: An agp driver
for _physical_ agp slots an the gtt driver that is used by the intel
drm modules. Split them to prevent any further confusion.

This patch just moves the code and includes intel-gtt.c in intel-agp.c
Later patches will untangle these two drivers further.

Previously, after setting up the Pineview CxSR state, i9xx_update_wm would
get called and overwrite our state.

BTW: We will disable the self-refresh and never enable it any more if we
can't find the appropriate the latency on pineview plaftorm. In such case
the update_wm callback will be NULL.

The bitmask macro is also defined to access the corresponding fifo
watermark register.

With new intel_encoder/intel_connector structure change, each supported
connector type on SDVO device will be created as a new 'intel_connector',
and all attached to one 'intel_encoder' for its SDVO port.

The SDVO encoder will handle SDVO protocol stuff, and each connector does
its own part of work now, like detection is only to check if current active
output is itself, etc.

- Fixed SDVO TV property creation failure by incorrect set target output call

Cougarpoint is the new PCH for Sandybridge CPU. This one resolves the
chipset change for display pipeline compared to previous Ibexpeak PCH.

Sandybridge/Cougarpoint has different FDI training parameters, so this also
makes seperate FDI training functions for IBX and CPT. Other change includes
new transcoder DPLL select function to set which DPLL for transcoder to pick
up.

And with another new transcoder C introduced in Cougarpoint, each connector
has new transcoder select bits. This one adds that change to light up VGA.

This was brought over from UMS, and used for a while until we decided
that drm_helper_resume_force_mode was easier and more reliable, since
it didn't require duplicating all the code deleted here.  We just
forgot to delete all that junk for a while.

This one replaces original param for intel_ddc_get_modes() with
DRM connector and i2c bus adapter instead. With explicit params,
we won't require that a single driver structure must hold connector
and DDC bus reference, which ease the conversion to splitted encoder/
connector model.

It also clears up for some cases that we would steal other DDC bus
for mode probe, like VGA analog DDC probe for DVI-I. Also it fixed
a bug in old DVI-I probe handling, that failed to restore origin
analog GPIO port.
