realtek: replace RTL93xx GPIO patches

Patches to support the SoC's GPIO controller for RTL930x and RTL931x
devices have been accepted upstream. Replace the current preliminary
patch with the upstream ones, excluding devictree binding changes.

The updated patches add GPIO IRQ balancing support on RTL930x, but this
cannot be used until these devices also support SMP.

+Subject: [PATCH 6/6] gpio: realtek-otto: Add RTL931x support
+
+The RTL931x SoC series has support for 32 GPIOs, although not all lines
+may be broken out to a physical pad.
+
+The GPIO bank's parent interrupt can be routed to either or both of the
+SoC's CPU cores by the GIC. Line-by-line IRQ balancing is not possible
+on these SoCs.
