Since the coprocessor state is tracked in a backup register, there is
no more need for tracking it in an environment variable : remove it.

Hi Lokesh
I would prefer you keep the rproc_elf32_sanity_check() API available
(not static).
Some u-boot drivers (eg ti_power_proc.c) handle binary (raw) firmwares
while some other handle ELF format ones.
We may think about drivers that can handle both formats.
rproc_elf32_sanity_check() can
Hi Lokesh,
Then a common rproc_elf_sanity_check() 32/64-bit common API would be
great :)
