Use chipaddr instead of volatile uint8_t * because when we access chips
in external flashers, they are not accessed via pointers at all.
Benefits: This allows us to differentiate between volatile machine
memory accesses and flash chip accesses. It also enforces usage
of chip_{read,write}[bwl] to access flash chips, so nobody will
unintentionally use pointers to access chips anymore. Some unneeded
casts are removed as well. Grepping for chip operations and machine
memory operations doesn't yield any false positives anymore.
Compile tested on 32 bit and 64 bit Linux.

flasher driver
Does not support reading or writing the fake chip yet.
flashrom --programmer dummy
also enables the dummy SPI controller driver.
Testing the dummy SPI driver revealed a RDID debug printing bug in the
SPI core. Fix that as well.

Print the return value of dummy_chip_read[bwl].
Align entries in programmer_table.
This is a cosmetic patch and has no effect on code flow.

Flash mapping/unmapping was performed without an abstraction layer,
so even the dummy flasher caused memory mappings to be set up. Add
map/unmap functions to the external flasher abstraction.
Fix a possible scribble-over-low-memory corner case which fortunately
never triggered so far.
With this patch, --programmer dummy works fine as non-root.

Usage:
flashrom --programmer dummy
This is a great way to test flashrom without root access.
