For Sandy Bridge boards with MRC raminit support, migrate as much
MRC settings to devicetree as possible, to stop mainboard code from
needlessly overwriting entire PEI data structure, so they will not
interfere with upcoming transition to one standard Haswell way of
providing SPD info to northbridge.
Some exceptions allowed are described below and in code comments.
SPD-related items are kept out of devicetree for now. They will be
migrated (with a different representation) with the Haswell SPD
transition.
google/{butterfly,link,parrot,stout} have max DDR3 frequency set in
pei_data to 1600 (2*800), but in devicetree to 666. The reason for the
difference seems to be problems with native raminit code. These are
converted into ternaries tied to CONFIG_USE_NATIVE_RAMINIT, with an
added "fix me" tag. asus/p8x7x-series also needs the same treatment,
based on testing various memory on p8z77-m hardware.
TEST=Builds on all affected boards. asus/p8z77-m still works with multiple RAM modules tested.

This disables MP table generation for the affected boards
since interrupt routing entries would now be completely missing.
The mechanism itself is flawed and redundant. The mapping
of integrated PCI devices' INTx pins to IOAPIC pins is
dependent of configuration registers and needs not appear
in the devicetree.cb files at all.
The write_smp_table implementation would skip writing
any entry delivering to destination IOAPIC ID 0. This
does not follow MP table specification.
There were duplicate calls to register_new_ioapic_gsi0(),
with another present under southbridge LPC device.
