Yauhen Kharuzhy 9942448837 s3cmci: Fix hangup in do_pio_write()
This commit fixes the regression what was added by commit
088a78af97 "s3cmci: Support transfers
which are not multiple of 32 bits."

fifo_free() now returns amount of available space in FIFO buffer in
bytes.  But do_pio_write() writes to FIFO 32-bit words.  Condition for
return from cycle is (fifo_free() == 0), but when fifo has 1..3 bytes
of free space then this condition will never be true and system hangs.

This patch changes condition in the while() to (fifo_free() > 3).
