pinctrl: renesas: rzg2l: Improve rzg2l_gpio_register()

Update rzg2l_gpio_register() to use driver data for chip->names
and check for gpio-range. This allows reusing the driver for
SoC's with different port pin definitions(eg:- RZ/G2UL SoC has
fewer ports compared to RZ/G2L and port pin definitions are
different).
