Subject: [PATCH v2] mips: dts: ingenic: x1000: Add PWM device tree node

Copied from the jz4740 devicetree and trimmed to 5 timers, which
is what the hardware supports.

Signed-off-by: Aidan MacDonald <aidanmacdonald.0x0@...il.com>
---
v2: Reduce regmap length since only the first 5 timers need to be accessed,
    and don't wrap the clock-names at 80 columns.
