dt-bindings: gpio: brcmstb: permit gpio-line-names property

gpio-line-names is a generic property that can be supported by any
GPIO controller, so permit it through the binding.

It is permitted to have a variable number of GPIOs per node based
on brcm,gpio-bank-widths, so define an arbitrary maximum number of
items based on current users.
