Uintptr_t-ify map_flash_region functions

Browse Source 
Unsigned long is not the right type for manipulating pointer values.
Since C99 there are suitable unsigned and signed types available, namely
uintptr_t and intptr_t respectively.

Use them in functions assigned to programmers' map_flash_region fields and
their callers where applicable.

This patch also changes the display width of all associated address values in
physmap.c to 16/8 hex characters depending on the actual size by
introducing a macro PRIxPTR_WIDTH and exploiting printf's * field width
specifier.

Corresponding to flashrom svn r1701.
