cfi_flash: support of long cmd in U-boot.
Some NOR flash chips needs support of commands with length grether than max value size of uchar. For example all M18 family chips use 0x1ff command in buffered write mode as value of program loops count.
Unfortunately this patch still breaks CFI support on sequoia board:
