[PATCH v2 3/3] gpio: brcmstb: remove custom 'brcmstb_gpio_set_names'

[Sergio Paracuellos <sergio.paracuellos@gmail.com>]

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.
