d37b7d89fd haswell: Add function to retrieve SPD addresses
And use it instead of directly writing to the MRC struct.

3ac92b7c93 haswell: Automatically determine system type
Check the PCH's LPC device ID to know the system type instead of relying
on hardcoded numbers. The `get_pch_platform_type` function is MRC-safe.

1be9f5841d haswell: Introduce ENABLE_DDR_2X_REFRESH Kconfig option
This Kconfig symbol allows doubling the memory's refresh rate, assuming
that the MRC actually cares about it. It is disabled by default except
on the mainboards which explicitly enabled this setting in `pei_data`.

d7bf3ad939 haswell: Compute disabled channel masks at runtime
All mainboards have a non-zero SPD address to implemented DIMM slots.
Knowing this, it is possible to compute the MRC slot population masks
automatically instead of hardcoding the values on each mainboard.

dd7470cb7e mb/asrock/b85m_pro4: Factor out common MRC settings
These settings are the same on all boards. Since the other boards
currently overwrite the struct contents, it doesn't make a difference.
To ease review, the same settings will be dropped from other boards in
separate commits, one board at a time.

b639707056 nb/intel/ironlake: Drop copy-pasted and dead code
This function was copy-pasted, comments included, from Sandy Bridge.
However, it is only called with 0x0044 as the northbridge's PCI ID.
Therefore, `bridge_silicon_revision() & BASE_REV_MASK` will always
evaluate to 0x40, which never equals `BASE_REV_SNB`, that is, 0x00.
As the condition is always false, treat this code as dead and drop it.

Following a similar reasoning, all direct comparisons against SNB
steppings will always be true, because `bridge_silicon_revision()`
returns at least 0x40 which is always larger than either `SNB_STEP_D0`
or `SNB_STEP_D1`. So, drop all but the code path that is actually used.

0df0c7e359 nb/intel/sandybridge/gma.c: Remove useless if condition
There's a useless check with both branches doing the same: enabling RC6
and disabling RC6p. In past, this condition would enable RC6p in IVB but
not on SNB. Then, at some point, RC6p was considered unstable and was
disabled, but the condition remained.

It's not needed so let's remove it.
