MIPS: Prune some target specific code out of prom.c
This code is not common enough to be in a shared file. It is also not
used by any existing boards, so just remove it.
[ralf@linux-mips.org: Dropped removal of irq_create_of_mapping which was
already removed by abd2363f6a5f1030b935e0bdc15cf917313b3b10
[irq_domain/mips: Allow irq_domain on MIPS]. Moved device_tree_init() and
dependencies to its sole user, the XLP code.]
