58b6409067 remoteproc: Move resource table load logic to find
Extend the previous operation of finding the resource table in the ELF
with the extra step of populating the rproc struct with a copy and the
size. This allows drivers to override the mechanism used for acquiring
the resource table, or omit it for firmware that is known not to have a
resource table.

This leaves the custom, dummy, find_rsc_table implementations found in
some drivers dangling.

0f21f9cc9d remoteproc: Merge rproc_ops and rproc_fw_ops
There are currently a few different schemes used for overriding fw_ops
or parts of fw_ops. Merge fw_ops into rproc_ops and expose the default
ELF-loader symbols so that they can be assigned by the drivers.

To keep backwards compatibility with the "default" case, a driver not
specifying the "load" operation is assumed to want the full ELF-loader
suit of functions.

4afc89d66c remoteproc: Support custom firmware handlers
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.

72854fb042 remoteproc: Move Elf related functions to separate file
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.
