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.] Signed-off-by: David Daney <david.daney@cavium.com> Cc: linux-mips@linux-mips.org Cc: devicetree-discuss@lists.ozlabs.org Cc: grant.likely@secretlab.ca Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/2946/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
