[PATCH v2 2/2] gpio: realtek-otto: Allow building for the RTL9311B

[Joshua Scott]

The Realtek RTL9311B is a network switch with integrated ARMv8 CPU. It
has the same GPIO controller as the RTL9310. Allow the driver to be
built for ARCH_REALTEK.

Changes in v2:
- Drop the "realtek,rtl9311b-gpio" match entry, as the RTL9311B now
  binds through "realtek,rtl9310-gpio" (Krzysztof)
- Retitle from "gpio: realtek-otto: Add RTL9311B support", as only the
  Kconfig change remains
