spl: nand: sunxi: introduce the nand_wait_int() helper

The pattern of polling on a status register until a bit is set or a
timeout occurs is repeated multiple times in the driver. Mutualize the
code by introducing the nand_wait_int() helper that does wait for the
bit to flip or returns an error in case of timeout.
