drivers/misc: add Aspeed LPC snoop driver
This driver enables the LPC snoop hardware on the ASPEED BMC
which generates an interrupt upon every write to an I/O port
by the host.
This is typically used to monitor BIOS boot progress by listening
to well-known debug port 80h.
The functionality in this commit just saves all snooped values
to a circular 2K buffer in the kernel, subsequent commits can
act on the values to do things with them.
