Add prototypes to (most of) src/sys/arch/pmax/pmax. (The un-protytyped parts still have pending merges with the Pica port.) Fix splx() glitches in pmax/clock.c. Delete old cpu/fpu identification from pmax/autoconf.c, use r4400/r4600/idt aware code from Pica port, now in mips/mips/mips_machdep.c. Delete unused multi-CPU autoconfiguration code; NetBSD/pmax does not support decsystem 5800s anyway.
