cgd d35047f37b Add a primitive driver for the PC-ish Programmable Peripheral Interface
and PC-ish keyboard controller.  (Actually, on alphas, the built-in PPI
(in the SIO) appears to be a lobotomized version of the original, but
i'd not call that a bad thing.)  This driver should eventually handle all
speaker tone requests and keyboard commands, but for now it just maps
the relevant ports and passes them on to the keyboard and mouse drivers,
which are now its children (rather than children of ISA).
