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.
