Subject: [PATCH V4 0/2] irqchip: loongson-eiointc: Add DT init support

Add EIOINTC irqchip DT support, which is needed for Loongson chips
that are DT-based and support EIOINTC, such as the Loongson-2K0500 chip.

---
V4:
- patch(1/2)
  - Simplify the definition of the reg attribute by declaring the entire
    chip configuration space directly.

V3:
- patch(1/2)
  - Drop quotes;
  - Drop interrupt-names;
  - Drop loongson,eio-num-vecs;
  - SoC-based compatibles instead of version-based compatibles.
- patch (2/2)
  - irq_set_handler_data() is used to get parent irq form DTS;
  - Set vec_count by judging compatibles.

V2:
- Add the dt-bindings file (1/2);
- patch(2/2)
  - Remove forgotten debugging messages;
  - Change compatible string name to "loongson,eiointc-1.0".
