spi: atmel: use endian agnostic IO
Use the endian agnositc IO functions instead of the __raw ones for when the driver is in use on big-endian systems. Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
