Sander Vanheule af6cd37f42 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 4/6] gpio: realtek-otto: Add RTL930x support
The RTL930x SoC series has support for 24 GPIOs, with the port order
reversed compared to RTL838x and RTL839x. The RTL930x series also has
two CPUs (VPEs) and can distribute individual GPIO interrupts between
them.
