Move hwaccess.h #include from flash.h to individual drivers. libflashrom users need flash.h, but they do not care about hwaccess.h and should not see its definitions because they may conflict with other hardware access functions and #defines used by the libflashrom user. Corresponding to flashrom svn r1549. Signed-off-by: Patrick Georgi <patrick.georgi@secunet.com> Acked-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net>
