Refine physical address mapping of flash chips
- Create distinct functions for mapping and unmapping for flash chips. - Map only when needed: map before probing and unmap immediately after it. Map again when a single chip was probed successfully before taking any actual actions and clean up afterwards. - Map special function chip registers centrally together with flash space instead of within (some) probing methods after successful probes. - Save the used base addresses of the mappings in struct flashctx as well. - Do not try to (un)map the zero-sized chip definitions that are merely hacks. This also fixes the printing of wrong warnings for these chip definitions introduced in r1765. Corresponding to flashrom svn r1847.
