All driver APIs (i2c, spi, gpio, etc.) return 'int' type, but pinmux APIs. So this patch changes the returning type from 'uint32_t' to 'int' from include/pinmux.h and fixes all pinmux drivers according. Besides keeping consistency between all drivers APIs, this patch is also applicable for the errno.h code transition. Pinmux drivers will return negative errno.h codes so returning 'int' is more suitable than 'uint32_t'.
