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 abd2363f6a
[irq_domain/mips: Allow irq_domain on MIPS].  Moved device_tree_init() and
dependencies to its sole user, the XLP code.]
