Introduce a type "chipaddr" to abstract the offsets within flash regions

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.

Corresponding to flashrom svn r519.
