gpio: uniphier: rework single device node model
First, I implemented this driver as per-bank model, but it was
a design mistake.
- There are 31 banks in the maximum case. It is painful to add
so many nodes to DT.
- The IRQ control registers are shared between banks. Per-bank
design is a problem for Linux. The counterpart for Linux turned
around to the single node model.
Rework based on the driver for Linux.
