cfi_flash: fix flash on BE machines with CFG_WRITE_SWAPPED_DATA
This got broken by commits 93c56f212c
[cfi_flash: support of long cmd in U-boot.]
That command needs to be in little endian format on BE machines
with CFG_WRITE_SWAPPED_DATA. Without this patch, the command 0xf0
gets saved on stack as 0x00 00 00 f0 and 0x00 gets written into
the cmdbuf in case portwidth = chipwidth = 8bit.
