Need to adjust the pll up for deep color modes.
Additionally, the atom bpc defines were wrong in certain
cases.

v2: set the adjusted clock to the pll clock for hdmi deep
color.  This fixes display and audio issues with deep color
as reported by Andy Furniss <adf.lists@gmail.com>

v3: set crtc_clock as well

v4: setcrtcinfo on the adjusted mode

v5: just use the adjusted clock for setting the pll

v6: only use the adjusted clock for hdmi

v7: only DCE5 and DCE6 and bpc > 8

Thanks to advanced RE of fglrx we finally know what exactly needs to be

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

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).

DCE 3.1 and 3.2 should be programmed in a different way than DCE 2 and
DCE 3. The order of setting registers and sets of registers are
different.
It's still unsure how we will handle DCE 3.1 vs. DCE 3.2, since they
have few differences as well.
For now separate DCE 2 and DCE 3 path, so we can work on it without a
risk of breaking DCE 3.1+.

This has been tested for possible regressions on DCE32 HD4550 (RV710).

This patch implements support for VRAM page table entry compression.
PTE construction is enhanced to identify physically contiguous page
ranges and mark them in the PTE fragment field. L1/L2 TLB support is
enabled for 64KB (SI/CIK) and 256KB (NI) PTE fragments, significantly
improving TLB utilization for VRAM allocations.

Linear store bandwidth is improved from 60GB/s to 125GB/s on Pitcairn.
Unigine Heaven 3.0 sees an average improvement from 24.7 to 27.7 FPS
on default settings at 1920x1200 resolution with vsync disabled.

DRM is pretty much the main user of this stuff (if we ignore the sysfs

This patch adds the related data set and expands the documentation.
Note that the SVGA bit occupies a different byte to all the existing
users of the established timing bits forcing a rework of the
ESTABLISHED_TIMINGS_BITS macro.
