Subject: [RFC PATCH] dt-bindings: hwlock: sun6i: Fix various warnings in binding

The allwinner,sun6i-a31-hwspinlock.yaml binding has a mismatched
$id and fails to compile the example due to undefined args specifier
values for clocks and resets. Fix both of these issues.

Fixes: f9e784dcb63f ("dt-bindings: hwlock: add sun6i_hwspinlock")

Hi Wilken,

This fixes the warnings for now on linux-next, but I think the example
should be including sun6i-a31-ccu.h files instead to be accurate, and
those files are missing the definitions for CLK_BUS_SPINLOCK and
RST_BUS_SPINLOCK. Feel free to send a newer version or do an incremental
patch on top.

regards
Suman
