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.
