The drm sysfs class suspend / resume methods could not distinguish
between different device types wich could lead to illegal type casts.
Use struct device_type and make sure the class suspend / resume callbacks
are aware of those. There is no per device-type suspend / resume. Only
new-style PM.

The code which takes probed modes and adds them to a connector eliminates
duplicate modes by comparing them using drm_mode_equal. That function
doesn't consider the type bits, which means that any modes which differ only
in the type field will be lost.
One of the bits in the mode->type field is the DRM_MODE_TYPE_PREFERRED bit.
If the mode with that bit is lost, then higher level code will not know
which mode to select, causing a random mode to be used instead.
This patch simply merges the two mode type bits together; that seems
reasonable to me, but perhaps only a subset of the bits should be used? None
of these can be user defined as they all come from looking at just the
hardware.

I had one report of flicker due to FIFO underruns on 845G. Scott was
kind enough to test a few patches and report success with this one.
Looks like 845G measures FIFO size slightly differently than other
chips, and we were also clobbering the FIFO burst length. Fixing both
of those issues gives him a healthy machine again.
Note that we still only adjust plane A's watermark in the 830/845
case. If someone is willing to test we could support a bigger variety
of dual-head 830/845 configurations with a bit more code.
Fixes fdo bug #19304 (again).

Now the DVO timing in LVDS data entry is obtained by using the
following step:
a. get the entry size for every LVDS panel data
b. Get the LVDS fp entry for the preferred panel type
c. get the DVO timing by using entry->dvo_timing
In our driver the entry->dvo_timing is related with the size of
lvds_fp_timing. For example: the size is 46.
But it seems that the size of lvds_fp_timing varies on the differnt
platform. In such case we will get the incorrect DVO timing entry
because of the incorrect DVO offset in LVDS panel data entry.
This also removes a hack on new IGDNG to get proper DVO timing.
Calculate the DVO timing offset in LVDS data entry to get the DVO timing
a. get the DVO timing offset in the LVDS fp data entry by using the
pointer definition in LVDS data ptr
b. get the LVDS data entry
c. get the DVO timing by adding the DVO timing offset to data entry
