of: Fix missing includes

This patch fixes missing includes from a number of .c files because
the code (wrongfully) depended on prom.h including them.  The include
of linux/of_address.h was removed in microblaze prom.h in commit
"of/address: Clean up function declarations" (sha1 id 22ae782f8), but
not fixed in some callers.  This patch fixes them up.
