misc: Add ASPEED mbox driver
This provides access to the mbox registers on the ast2400 and ast2500
SoCs.
This driver allows arbitrary reads and writes to the 16 data registers as
the other end may have configured the mbox hardware to provide an
interrupt when a specific register gets written to.
OpenBMC-Staging-Count: 6
[joel: move to drivers/misc as this isn't a mailbox driver]
