Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of issues

- moves out of nouveau_bios.c and demagics the logical state definitions
- simplifies chipset-specific driver interface
- makes most of gpio irq handling common, will use for nv4x hpd later
- api extended to allow both direct gpio access, and access using the
  logical function states
- api extended to allow for future use of gpio extender chips
- pre-nv50 was handled very badly, the main issue being that all GPIOs
  were being treated as output-only.
- fixes nvd0 so gpio changes actually stick, magic reg needs bashing

drm/nouveau/mxm: initial implementation of dcb sanitisation

The DCB table provided by the VBIOS on most MXM chips has a number of
entries which either need to be disabled, or modified according to the
MXM-SIS Output Device Descriptors.

The x86 vbios code usually takes care of this for us, however, with the
large number of laptops now with switchable graphics or optimus, a lot
of the time nouveau is responsible for POSTing the card instead - leaving
some fun situations like, plugging in a monitor and having nouveau decide
3 connectors actually just got plugged in..

No MXM-SIS fetching methods implemented yet.

drm/nouveau/disp: parse connector info directly in nouveau_connector.c

Another case where we parsed vbios data to some structs, then again use
that info once to construct another set of data.  Skip the intermediate
step.

This is also slightly improved in that we can now use DCB 3.x connector
table info, which will allow NV4x to gain hotplug support, and to make
quirks for SPWG LVDS panels unnecessary.

drm/nouveau/i2c: handle bit-banging ourselves

i2c-algo-bit doesn't actually work very well on one card I have access to
(NVS 300), random single-bit errors occur most of the time - what we're
doing now is closer to what xf86i2c.c does.

The original plan was to figure out why i2c-algo-bit fails on the NVS 300,
and fix it.  However, while investigating I discovered i2c-algo-bit calls
cond_resched(), which makes it a bad idea for us to be using as we execute
VBIOS scripts from a tasklet, and there may very well be i2c transfers as
a result.

So, since I already wrote this code in userspace to track down the NVS 300
bug, and it's not really much code - lets use it.
