ARM: dts: aspeed: rainier: Add CFAM reset GPIO
The GPIO on Q0 is used for resetting the CFAM of the processor that the ASPEED master is connected to. The signal is wired as active high on the first pass systems. Reviewed-by: Andrew Jeffery <andrew@aj.id.au> Signed-off-by: Joel Stanley <joel@jms.id.au>
