returns the location of the resource table in shared memory
after loading.

Refactor rproc_elf_find_rsc_table() and split out the scanning
for the section header named resource table. This is done to
prepare for loading firmware once.

Merge tag 'remoteproc-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc
Pull remoteproc update from Ohad Ben-Cohen:
- custom binary format support from Sjur Brændeland
- groundwork for recovery and runtime pm support
- some cleanups and API simplifications
Fix up conflicts in drivers/remoteproc/remoteproc_core.c due to clashes
with earlier cleanups by Sjur Brændeland (with part of the cleanups
moved into the new remoteproc_elf_loader.c file).
* tag 'remoteproc-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc:
MAINTAINERS: add remoteproc's git
remoteproc: Support custom firmware handlers
remoteproc: Move Elf related functions to separate file
remoteproc: Add function rproc_get_boot_addr
remoteproc: Pass struct fw to load_segments and find_rsc_table.
remoteproc: adopt the driver core's alloc/add/del/put naming
remoteproc: remove the get_by_name/put API
remoteproc: support non-iommu carveout assignment
remoteproc: simplify unregister/free interfaces
remoteproc: remove the now-redundant kref
remoteproc: maintain a generic child device for each rproc
remoteproc: allocate vrings on demand, free when not needed
Firmware handling is made customizable.
This is done by creating a separate ops structure for the
firmware functions that depends on a particular firmware
format (such as ELF). The ELF functions are default used
unless the HW driver explicitly injects another firmware
handler by updating rproc->fw_ops.
The function rproc_da_to_va() is exported, as custom
firmware handlers may need to use this function.

Prepare for introduction of custom firmware loaders by
moving all ELF related handling into a separate file.
The functions: rproc_find_rsc_table(), rproc_fw_sanity_check(),
rproc_find_rsc_table() and rproc_get_boot_addr() are moved
to the new file remoteproc_elf_loader.c. The function
rproc_da_to_va() is made non-static and is declared in
remoteproc_internal.h
No functional changes are introduced in this patch.
