Since I was a bit confused at first at seeing a new Kconfig symbol with
no accompanying code to implement its functionality (until I grepped
around a bit and saw why), it might be nice to note in the commit
message that the logic to support this already exists in the ast2500
platform code and just didn't have an accompanying Kconfig option until
now.
