The original line,
WREG_DAC(MGA1064_PIX_CLK_CTL_CLK_DIS, tmp);
wrote tmp into MGA1064_PIX_CLK_CTL_CLK_DIS, where
MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into
MGA1064_PIX_CLK_CTL. Change the line to write properly into
MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use
the same pattern (but work correctly), so this patch updates them all
to use this new (slightly more efficient) write pattern. The WREG_DAC
macro was causing the DAC_INDEX register to be set to the same value
twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX
is already at the value we want.

This patch introduce Frame Buffer Compression (FBC) support for IVB,
without enabling it by default.
It adds a new function gen7_enable_fbc to avoid getting
ironlake_enable_fbc messed with many IS_IVYBRIDGE checks.
v2: Fixes from Ville.
* Fix Plane. FBC is tied to primary plane A in HSW
* Fix DPFC initial write to avoid let trash on the register.
v3: Checking for bad plane on intel_update_fbc() as Chris suggested.
v4: Ville pointed out that according to BSpec FBC_CTL bits 0:3 must be 0.
v5: Up to v4 this work was entirely focused on Haswell. However Ville
noticed I could reuse the FBC work done for HSW and get FBC for free
at Ivybridge. So it makes more sense enable FBC for IVB first.
FBC for HSW comming on next patches. We are just not enabling it by
default on IVB.

This seems to be an impressive piece of copy&pasta lore. I've
checked all docs and on most platforms these bits are all MBZ, with
the exception of the SDVO pixel multiplier on gen3. On gen4 that
moved to a special DPLL_MD registers.
No indication whatsoever that we actually need this for native
TV-out support. I suspect this started as a hack when we didn't
yet have proper pixel multiplier support in place for SDVO TV, but
then got stuck in a life of its own.
Just rip it out.

TV-out uses the same reference clock as everyone else. The only
difference seems to be in the slightly different CB tuning limit.
Note that PLL_REF_INPUT_TVCLKINBC is a reserved value on ilk+. Also
strictly speaking we don't support native TV-out on ilk+, hence all
that code is dead. But Bspec still contains some residual mentions of
native TV-out on some pch-split platforms, so I've figured it doesn't
hurt to keep the code around a bit longer (e.g. in the cb tune
function).
