gpio: brcmstb: remove custom 'brcmstb_gpio_set_names'
Gpiolib core code has been updated to support setting friendly names
through properly 'gpio-line-names'. Instead of redefine behaviour here
to skip the core to be executed, just properly assign the desired offset
per bank to get in the core the expected behaviour.
