spi/pl022: Explicitly truncate large bitmask
When building on 64 bit architectures the use of bitwise negation generates constants larger than 32 bits which won't fit in u32s used to represent 32 bit register values on the device. Explicitly cast to let the compiler know that the higher bits are not significant and can be discarded. Signed-off-by: Mark Brown <broonie@linaro.org>
