Further cleanup and unification of i2c code

- unify the ddc and i2c code
- add gpio mask support for legacy chips
- remove the magic gpio dance for ancient monitors
  (if you have an ancient monitor that ddc stops
   working on let me know).  This should speed up DDC
  on legacy chips.

-- radeon sw gpio i2c --
4 sets of gpio registers for clk and data and corresponding bit masks
mask - locks the gpio for use by sw
get  - reads the value off the gpio pad
put  - sets the gpio direction to output
a    - "other stuff" On legacy chips you clear them if you want
       to use a gpio for i2c.  In some cases they are used for the
       output value when the gpio in the output state.
