switch: make LED port_mask file write handler use kstrtoul() function
This patch changes swconfig_trig_port_mask_store() handler to utilize kstrtoul() function instead of call to obsolete simple_strtoul(). Thanks to this change, new handler takes less memory and makes port_mask special file accept not only hexadecimal, but also decimal and octal numbers.
