Split the quirks and i2c_rec assignment into separate
functions used by both radeon_lookup_i2c_gpio() and
radeon_atombios_i2c_init(). This avoids duplicating code
and cases where quirks were only added to one of the
functions.

NI chips no longer load the MC ucode in the asic_init sequence so
the asic comes up in a basic mode with low engine/memory clocks and
a voltage. Once the MC ucode is loaded by the driver the card
can be programmed to it's proper default clocks and voltage. As such
the default clocks in the firmware info table as the post clocks, not
the default running clocks. Track the default post clocks and default
running clocks separately to handle this.

Acer laptop (TravelMate 5730G) has an HDMI connector
on the laptop and a DVI connector on the docking station
and both share the same encoder, hpd pin, and ddc line.
The bios connector table reflects this and is technically
correct, however, we drop the DVI connector here since
xrandr has no concept of encoders (only crtcs and connectors)
and will try and drive both connectors with different crtcs
which isn't possible on the hardware side and leaves no crtcs
for LVDS or VGA.
