ASoC: ab8500-codec: Drop bank prefix from AB8500_GPIO_DIR4_REG register define
The AB8500_GPIO_DIR4_REG register define has the bank for the register in the upper 8 bits and the register itself in the lower 8 bits. When passing it to abx500_{set,get}_register_interruptible() the upper bits get truncated which generates the following warning from sparse: sound/soc/codecs/ab8500-codec.c:1972:53: warning: cast truncates bits from constant value (1013 becomes 13) sound/soc/codecs/ab8500-codec.c:1980:53: warning: cast truncates bits from constant value (1013 becomes 13) The bank is passed separately to abx500_{set,get}_register_interruptible() so the code works fine as it is. Given that all users of AB8500_GPIO_DIR4_REG always truncate the upper 8 bits just remove them from the define. Also remove the unnecessary casts to u8.
