This change fixes the constants which select a clock source which get some

Now that we are executing VbInit() in coreboot we can end up
in a situation where the recovery reason is consumed during
VbInit (end of romstage) and then the EC is rebooted to RO
during ramstage EC init, thereby losing the recovery reason.
Two possiblities are to remove the EC check+reboot from ramstage
and let it happen in depthcharge. This however means that the
system has to boot all the way into depthcharge and then reboot
the EC and the system again.
Instead if we do a check in romstage before VbInit() is called
then we can reboot the EC into RO early and avoid booting all
the way to depthcharge first.
This change adds a ramstage version the EC init function and
calls it from the shared romstage code immediately after the
PCH decode windows are setup.

When modifying the page tables, use writel to ensure the writes happen, flush
the page tables themselves to ensure they're visible to the MMU if it doesn't
look at the caches, and invalidate the right TLB entries.
The first two changes are probably safer but may not be strictly necessary.
The third change is necessary because we were invalidating the TLB using i
which was in megabytes but using an instruction that expects an address in
bytes.
One symptom of this problem was that the framebuffer, which was supposed to be
marked uncacheable, was only being partially updated since some of the updates
were still in the cache. With this change the graphics show up correctly.

The page tables need to be aligned to a 16KB boundary and are 16KB in size.
The CBMEM allocator only guarantees 512 byte alignment, so to make sure
things are where they're supposed to be, the code was allocating extra space
and then adjusting the pointer upwards. Unfortunately, it was adding the size
of the table to the pointer first, then aligning it. Since it allocated twice
the space of the table, this had the effect of moving past the first table
size region of bytes, and then aligning upwards, pushing the end of the table
out of the space allocated for it.
You can get away with this if you push things you don't care about off the
end, and it happened to be the case that we were allocating a color map we
weren't using at the start of the next part of cbmem.

These are not specific to Intel. Further work needs to be done to
combine these with MMCONF_SUPPORT in arch/io.h.

Define at one place whether to use IO 0xcf8/0xcfc or MMIO via
MMCONF_BASE_ADDRESS for PCI configuration access funtions in ramstage.
The implementation of pci_default_config() always returned with
pci_cf8_conf1. This means any PCI configuration access that did
not target bus 0 used PCI IO config operations, if PCI MMIO config
was not explicitly requested.
