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.

The TV detection logic is not reliable on the Cantiga platform.
Sometimes the TV will be misdetected as the following two cases:
- TV is misdetected on some laptops. e.g. There is no TV connector
port or no TV is attached. But the TV is shown as connected.
- TV connector type is misdetected. e.g. the component TV is
attached, but the TV is shown as S-video type.
According to the hardware requirement, the TV sense state bits of TV DAC
register should be cleared to zero on Cantiga platfrom.

The intel_output naming is inherited from the UMS code, which had a
structure of screen -> CRTC -> output. The DRM code has an additional
notion of encoder/connector, so the structure is screen -> CRTC ->
encoder -> connector. This is a useful structure for SDVO encoders
which can support multiple connectors (each of which requires
different programming in the one encoder and could be connected to
different CRTCs), or for DVI-I, where multiple encoders feed into the
connector for whether it's used for digital or analog. Most of our
code is encoder-related, so transition it to talking about encoders
before we start trying to distinguish connectors.
This patch is produced by sed s/intel_output/intel_encoder/ over the
driver.

In order to use disks larger than 2TiB on Windows XP, it is necessary to
use 4096-byte logical sectors in an MBR.
Although the kernel storage and functions called from msdos.c used
"sector_t" internally, msdos.c still used u32 variables, which results in
the ability to handle XP-compatible large disks.
This patch changes the internal variables to "sector_t".
Daniel said: "In the near future, WD will be releasing products that need
this patch".
