CFI: allow for dynamically determined flash sizes and addresses
The CFI driver allowed only for static initializers in the CFG_FLASH_BANKS_LIST definition, i. e. it did not allow to map several flash banks contiguously if the bank sizes were not known in advance, which kind of violates U-Boot's design philosophy. (will be used for example by the TQM8xxL boards) Signed-off-by: Wolfgang Denk <wd@denx.de>
