protocol: Introduce protocol_reset()

protocol_reset() encapsulates the actions necessary to return the LPC
state to what's required to boot the host. This is backend dependent;
for the mtd backend we can simply point the bridge at the host flash
AHB mapping, and for the virtual pnor we want to rearrange the content
of the LPC reserved memory (leaving the bridge pointed there). In either
case the state of the FWH address space is distured, so inform the host
as necessary.
