[PATCH v2 1/1] gpio-f7188x: fix chip name and pin count on Nuvoton chip

[Henning Schild <henning.schild@siemens.com>]

In fact the device with chip id 0xD283 is called NCT6126D, and that is
the chip id the Nuvoton code was written for. Correct that name to avoid
confusion, because a NCT6116D in fact exists as well but has another
chip id, and is currently not supported.

The look at the spec also revealed that GPIO group7 in fact has 8 pins,
so correct the pin count in that group as well.

Fixes: d0918a84aff0 ("gpio-f7188x: Add GPIO support for Nuvoton NCT6116")
