This implements support for devices using AMD Geode companion chip
CS5536 that have the Boot ROM on NOR flash that is directly connected to
FLASH_CS3 (Boot Flash Chip Select). We need to write enable it in the
NORF_CTL MSR register for flashrom to be able to write to it, including
JEDEC probe commands.

This patch allows us to stop using AMD gx_utils.ko for BIOS flashing on
the DBE61.

Some vendors like Programmable Micro Corp (PMC) need this. Both the
serial and parallel flash JEDEC detection routines would benefit from a
parity/sanity check of the vendor ID. Will do this later.

Add support for the PMC Pm25LV family of SPI flash chips.

Make the vendor name optional in the -m flashrom parameter when there's only one board name that matches

The full syntax still works, and is required when two vendors have
boards with the same names.

The continuation ID code does not go further than checking for IDs of
the type 0x7fXX, but does this for vendor and product ID. The current
published JEDEC spec has a list where the largest vendor ID is 7 bytes
long, but all leading bytes are 0x7f. The list will grow in the future,
and using a 64bit variable will not be enough anymore.
Besides that, it seems that the location of the ID byte after the first
continuation ID byte is very vendor specific, so we may have to revisit
that code some time in the future.

(Suggestion for a new encoding:
Use a two-byte data type for the ID, the lower byte contains the only
non-0x7f byte, the upper byte contains the number of 0x7f bytes used as
prefix, which is the bank number minus 1 the vendor ID appears in.)

This fixes a few vendor IDs to conform with JEDEC publication 106W
(JEP106W), adds some device IDs and provides information about
non-conforming IDs. The EON change is left to the patch adding EON
chips.

This patch should have no effect on code generation.

To make it easier to add new SPI chips to flashchips.c, rename functions
with multiple possible opcodes from linear numbering at the end (_1, _2)
to include the opcode at the end (_60, _c7).

That way, you only have to take a short look at the data sheet and
choose the right function by appending the opcode listed in the data
sheet. No functional changes.

variations in chip delays with a factor of 2 safety margin.
