Adding the ability to get a physical address from point() in addition
to virtual address. This physical address is required for XIP of
userspace code from flash.

Address a number of small issues mainly regarding the output made by this
driver to dmesg:
- Some of the blkmtd's had not been changed to block2mtd which caused
display problem
- the parse_err() macro was displaying "block2mtd: " twice

I have been prime author and maintainer of block2mtd from day one, but
neither MAINTAINERS nor the module source makes this fact clear. And while
I'm at it, update my email addresses tree-wide, as the old address
currently bounces and change my name to "joern" as unicode will likely
continue to cause trouble until the end of this century.

After writing to a Dataflash page, the built-in compare operation is
used to check that the page was successfully written. A logic bug in
checking the results of the comparison currently causes the compare to
never fail.
This bug was originally in the legacy at91_dataflash.c driver.

This reverts commit 340ea370c2.
It's not needed given the other m25p80 patch (which now handles
at26 "dataflash" as well as most other standard SPI flash chips),
and requires a controller driver that won't be merged upstream
(supplanted by drivers/spi/atmel_spi.c) ... the submitter of
that at91_dataflash26.c driver concurred.

Update chip ID tables in m25p80 to handle more SPI flash chips, matching
datasheets. All of these can use the same core operations and are newer
chips that support the JEDEC "read id" instruction:
- Atmel AT25 and AT26 (seven chips)
- Spansion S25SL (five chips)
- SST 25VF (four chips)
- ST M25, M45 (five more chips)
- Winbond W25X series (seven chips)
That JEDEC instruction is now used, either to support a sanity check on the
platform data holding board configuration data, or to determine chip type
when it's not included in platform data. In fact, boards that don't need a
standard partition table may not need that platform data any more.
For chips that support 4KiB erase units, use that smaller block size instead
of the larger size (usually 64KiB); it's less wasteful. (Tested on W25X80.)
