ASoC: adau1977: Fix truncation warning on 64 bit architectures

Negating ADAU1977_BLOCK_POWER_SAI_LDO_EN creates an unsigned long constant with all bits set which on 64 bit architectures needs to be truncated to an unsigned int, generating a warning. Add an explicit cast since we know this is OK. Signed-off-by: Mark Brown <[email protected]> Acked-by: Lars-Peter Clausen <[email protected]>
