Subject: [PATCH V2 0/2] Loongson: irqchip: Add loongson-eiointc DT init support

Hi all:

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

We need to handle the "parent_irq" and "eio-num-vecs" parameters passed
from DTS.

Thanks.

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