Recent RE efforts revealed ops performed by fglrx during HDMI setup.
This mostly adds masks to r/w ops plus few single missing bits.

This has been tested for possible regressions on:
1) DCE2 HD2400 (RV610)
2) DCE3 HD3470 (RV620)

What initially seemed to be a typo in fglrx (using register 0x740c
instead of 0x74dc) appeared to be a correct behavior. DCE3 has ACR and
CRC registers swapped which explains why we needed
WREG32(HDMI0_AUDIO_CRC_CONTROL + offset, 0x1000);

This has been tested for possible regressions on DCE3 HD3470 (RV620).

pci config reset is a low level reset that resets
the entire chip from the bus interface.  It can
be more reliable if soft reset fails.

There's not much information still available on
r6xx, so r6xx is based on guess-work.

The FMT blocks control how data is sent from the backend
of the display pipe to to monitor.  Proper set up of the
FMT blocks are required for 30bpp formats.  Additionally,
dithering can be enabled on for better display with 18 and
24bpp displays.  The exception is LVDS/eDP which atom
takes care of in the SelectCRTC_Source table.  For now
just enable truncation until we test dithering more.

Checking of the second colorbuffer was skipped on r700, because
CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff,
so we must set the number of samples of the second colorbuffer to 1 in order
to pass the CS checker.
