This removes all the duplicated code and logic and leverages
the existing ones in libraries themselves. The current side
effect is that protection cannot be fully enabled because the
read, write, and write enable command are not exposed in struct
spi_flash currently. That support can be revised if protection
scheme makes sense for our use-cases once it's better understood.

According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.
How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

ACPI MMIO decode enable bit is the second LSB, not the first LSB.
Additionally create another enable function for older families where

It does not seem to impact any current board, but may be crucial for

very early. Most likely this bit is set by AGESA right now.
