dt-bindings: misc: aspeed,ast2400-cvic: Convert to DT schema

Address warnings such as:

arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-galaxy100.dtb: interrupt-controller@1e6c0080: 'valid-sources'

dt-bindings: misc: aspeed,ast2400-cvic: Convert to DT schema

Address warnings such as:

arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-galaxy100.dtb: interrupt-controller@1e6c0080: 'valid-sources' does not match any of the regexes: 'pinctrl-[0-9]+'

and

arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-galaxy100.dtb: /ahb/copro-interrupt-controller@1e6c2000: failed to match any schema with compatible: ['aspeed,ast2400-cvic', 'aspeed-cvic']

Note that the conversion to DT schema causes some further warnings to
be emitted, because the Aspeed devicetrees are not in great shape. These
new warnings are resolved in a separate series:
