pinctrl: bcm283x: Store the return value of dev_read_u32_default to int

Browse source 
Currently, the return value of dev_read_u32_default is stored in an u32,
causing the subsequent "if (function < 0)" to always be false:

u32 function;
...
function = dev_read_u32_default(config, "brcm,function", -1);
if (function < 0) {
        debug("Failed reading function for pinconfig %s (%d)\n",
                      config->name, function);
        return -EINVAL;
}

Make "function" variable an int to fix this.
