Subject: [PATCH v6 3/9] arm64: allwinner: a64: add NMI (R_INTC) controller on A64

Allwinner A64 SoC features a R_INTC controller, which controls the NMI
line, and this interrupt line is usually connected to the AXP PMIC.

Add support for it.

Signed-off-by: Icenowy Zheng <icenowy@...c.io>
---
Changes in v4:
- Changes it to use R_INTC binding and change node label to r_intc.
- Fixed MMIO region.
- Dropped Chen-Yu's ACK due to big change.
Changes in v2:
- Added Chen-Yu's ACK.
