Add lock printing for AMIC A25L05PT, A25L05PU, A25L10PT, A25L10PU,

to a25.c.

Add lock printing for Atmel AT26DF081A, AT26DF161, AT26DF161A,
AT26DF321.

Move Atmel AT25*/AT26* lock related functions originally added in r1115
from spi25.c to at25.c.

For SPI chips the lock printing was handled by one common function, but
sharing a common function which only is a big switch() statement doesn't
make sense, especially if we can define lock printing functions per
flash chip anyway.

The printlock function pointer in struct flashchip is used to print
status register and locking information, and serves as replacement for
implicit status register and lock printing during probe. That code will
later be changed to store locking info in a machine- accessible data
structure so flashrom can handle locked regions...

Remove the array spi_programmer, replace it by dynamic registration
instead. Also initially start with no busses supported, and switch to
the default non-SPI only for the internal programmer.

Also this patch changes the initialization for the buses_supported variable
from "everything-except-SPI" to "nothing". All programmers have to set the
bus type on their own, and this enables register_spi_programmer to just add
the SPI both for on-board SPI interfaces (where the internal programmer
already detected the other bus types), as well as for external programmers
(where we have the default "none").

Handle board-specific quirks in three phases:
1. Before Super I/O probing (e.g. blacklisting of some Super I/O probes,
or unhiding the Super I/O)
2. Before the laptop enforcement decision (e.g. whitelisting a laptop
for flashing)
3. After chipset enabling (all current board enables)

Implementation note: All entries in board_pciid_enables get an
additional phase parameter. Alternative variants (3 tables instead of 1)
also have their downsides, and I chose table bloat over table
multiplication).

With this patch, it should be possible to whitelist supported laptops
with a matching entry (phase P2) in board_pciid_enables which points to
a function setting laptop_ok=1. (In case DMI is broken, matching might
be a little bit more difficult, but it is still doable.)

Flashrom currently only supports exactly one Super I/O or Embedded
Controller, and this means quite a few notebooks and a small subset of
desktop/server boards cannot be handled reliably and easily.
Allow detection and initialization of up to 3 Super I/O and/or EC chips.

WARNING! If a Super I/O or EC responds on multiple ports (0x2e and
0x4e), the code will do the wrong thing (namely, initialize the hardware
twice). I have no idea if we should handle such situations, and whether
we should ignore the second chip with identical ID or not. Initializing
the hardware twice for the IT87* family is _not_ a problem, but I don't
know how well IT85* can handle it (and whether IT85* would listen at
more than one port anyway).

It is extremely unlikely that a chip not requiring delays in probe does
require them in erase. We observed unreliable erasing with a SST49LF004A
with these delays, so remove them if the are not required.

In review, I got the hint that "probe_jedec goes further by making that
call conditional on nonzero delay". I decided to ignore that. For
internal_delay, the small amount of clock cycles wasted for calling
programmer_delay(0) is negligible compared to LPC cycle times. It might
be an issue for 5 wasted bytes on the serial line in serprog. OTOH,
flash erase is still slow compared to 6*5 bytes on a serial port at
reasonable speed.

As the comment indicates, that function is not a chip erase function
at all, but a function calling a block eraser in a loop. So it adds
no extra value to what we already have in the block_eraser
infrastructure.

Furthermore, that function assumes a uniform sector size layout, but
is referenced from flash chip with non-uniform sector size layout, which
is just wrong.
