There's no generic way to tell whether a mainboard has an EC or not.
Making Kconfig symbols for these options seems overkill, too. So, just
put them on the devicetree. Also, drop unnecessary assignments when the
board's current value is zero, as the struct defaults to zero already.

Current code only cares whether the PCH is LP or not. However, MRC wants
to differentiate between desktop and non-LP mobile platforms as well. As
the PCH is soldered onto the mainboard, add a facility to retrieve which
platform coreboot is running on by checking the PCH's LPC device ID. The
only user of the `pch_silicon_type` function is the `pch_is_lp` function
so replace the former with the new `get_pch_platform_type` function. The
function needs to be defined in both romstage and ramstage where PCI ops
have different signatures, hence the two copies.

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`.

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.

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.

The DxxIR (Device xx Interrupt Route) registers in RCBA are 16-bit wide,
so do not use 32-bit operations to program them.
Note that the DxxIP (Device xx Interrupt Pin) registers are 32-bit, so
using 32-bit operations on them is correct.

The current value of 0x1000 would overlap the first PCI bridge IO
window. As we commonly reserve IO range 0x0 .. 0x1000 for LPC and
integrated device use, change SMBUS_IO_BASE to 0x400. This is the
prevalent value among Intel southbridges, too.
