Subject: [PATCH v2 3/3] 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.

Since it will be a v3, reflow commit messages to occupy a little bit
more available space (per line). Something ~72-75 characters per line
is good balance.
