[SPARC64]: SMP build fixes.

With the move of ldom_startcpu_cpuid() into smp.c some other
things need to follow along:

1) smp.c is not a driver so we can't use "PFX" macro in the
   printk calls.

2) smp.c now needs asm/io.h and asm/hvtramp.h, ds.c no longer
   does

3) kimage_addr_to_ra() also needs to move into smp.c

While we're here, update copyright info and my email address
in smp.c
