Add some helpers that can be called by the drivers to load the firmware resource table from an elf32 / elf64 image. The stm32 remoteproc driver makes use of it, to load the resource table before the elf image itself.
This series applies on top of the "remoteproc: Add support for R5F and DSP processors" series [1] proposed by Lokesh Vutla which introduces the elf64 support.
