ath79: restore pin state on probe for ar934x-spi
If bootloader doesn't terminate its last spi operation properly
before starting kernel, our first transfer in kernel becomes a
continuous transfer to that request instead of a new one.
Fix this flaw by restoring IOC register, which restored all pin
state to default.
