Subject: [PATCH] dt-bindings: mfd: aspeed-lpc: Add missing "clocks" property on lpc-snoop node

The ASpeed lpc-snoop nodes have a "clocks" property which isn't
documented. It looks like all the LPC child devices have the same clock
source. Perhaps it is the parent device that should have the clock, but
it's too late for that. The driver for lpc-snoop requires a clock to be
present.
