flash: Fix CFI buffer size bug
Fix bug introduced by 9c048b523413ae5f3ff34e00cf57569c3368ab51.
The cfi_flash.c driver cast the flash buffer size to a uchar in
flash_write_cfibuffer(). On some flash parts, (tested on Numonyx
part PC32F512M29EWH), the buffer size is 1KB. Remove the cast to
uchar to enable buffer sizes to be larger.
