Rob Herring 43d78445da dt-bindings: interrupt-controller: Drop unneeded quotes
Cleanup bindings dropping unneeded quotes. Once all these are fixed,
checking for this can be enabled in yamllint.

maintainers:
- Jiaxun Yang <jiaxun.yang@flygoat.com>
description: |
This interrupt controller is found in the Loongson-3 family of chips and
Loongson-2K1000 chip, as the primary package interrupt controller which
can route local I/O interrupt to interrupt lines of cores.

description: |
This property points how the children interrupts will be mapped into CPU
interrupt lines. Each cell refers to a parent interrupt line from 0 to 3
and each bit in the cell refers to a child interrupt from 0 to 31.
If a CPU interrupt line didn't connect with liointc, then keep its
cell with zero.
