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.

Changes since v1:
-Do not fixup the DeviceTree to track the stm32 coprocessor state. Instead of
 this, use a dedicated register.

Fabien Dessenne (6):
  remoteproc: elf_loader: Add elf resource table load support
  stm32mp1: declare backup registers for coprocessor
  stm32mp1: reset coprocessor status at cold boot
  remoteproc: stm32: track the coprocessor state in a backup register
  stm32mp1: remove copro_state environment variable
  remoteproc: stm32: load resource table from firmware
