Use struct flashctx instead of struct flashchip for flash chip access
Struct flashchip is used only for the flashchips array and for
operations which do not access hardware, e.g. printing a list of
supported flash chips.
struct flashctx (flash context) contains all data available in
struct flashchip, but it also contains runtime information like
mapping addresses. struct flashctx is expected to grow additional
members over time, a prime candidate being programmer info.
struct flashctx contains all of struct flashchip with identical
member layout, but struct flashctx has additional members at the end.
The separation between struct flashchip/flashctx shrinks the memory
requirement of the big flashchips array and allows future extension
of flashctx without having to worry about bloat.
Corresponding to flashrom svn r1473.
