powerpc: Print decimal values in prom_init.c 

Currently we look pretty stupid when printing out a bunch of things in
prom_init.c.  eg.

  Max number of cores passed to firmware: 0x0000000000000080

So I've change this to print in decimal:

  Max number of cores passed to firmware: 128 (NR_CPUS = 256)

This required adding a prom_print_dec() function and changing some
prom_printk() calls from %x to %lu.
