Add lock printing for Atmel AT26DF081A, AT26DF161, AT26DF161A,

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 correctly.

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.

Print lock status for all supported Winbond W39* chips:
W39V040A, W39V040B, W39V040C, W39V040FA, W39V040FB, W39V040FC,
W39V080A, W39V080FA, W39V080FA (dual mode).
Fill in correct probe timing for Winbond W39V040C and W39V080FA.
Please note that the W39V040B/W39V040FB pair has identical IDs,
identical read/write/erase, but locking differs. Same applies to
W39V040C/W39V040FC. This causes double detection on chipsets which
support LPC and FWH, making flashing more difficult because the user
has to select the correct chip. This is called the evil twin problem.
A better evil twin handling (patch available) will resolve that problem.

The project is in the the process of designing and making a complete,
open source, graphics card. More info at http://wiki.opengraphics.org.
The first development card is a PCI add in card containing a couple of
FPGAs and a couple of serial flash chips (amongst other things). The
FPGAs are called XP10 and S3 (their part numbers). The XP10 contains its
own flash and does not need to be programmed by flashrom - it ensures
that the device can enumerate on the PCI bus without needing further
configuration.
The larger FPGA is the S3. This is configured from a large SPI flash
(2 MBytes). The second SPI flash is used to store the VGA BIOS. It is
smaller (128 KBytes). This patch adds support for programming either of
the two SPI flash chips.
The programmer device takes one configuration option which selects which
of the two flash chips is accessed. This must be set to either "cprom"
or "bprom". (The project refers to the two chips as "cprom" / "bprom",
"s3" and "bios" are more readable alternatives).
Add support for SST SST25VF010 (REMS). Mark SST SST25VF016B as tested
for write.

Flashrom had an implicit erase-on-write for most flash chip and
programmer drivers, but it was not entirely consistent.
Some drivers had their own hand-rolled partial update functionality
which made handling partial updates from generic code impossible.
Move implicit erase out of chip drivers, and kill some dead erase
functions at the same time. A full chip erase is now performed in the
generic code for all flash chips on write, and after that the whole chip
is written.
