Add MAIN domain R5FSS0 remoteproc support from spl. This enables loading the elf firmware in SPL and starting the remotecore.
In order to start the core, there should be a file with path "/lib/firmware/j7-main-r5f0_0-fw" under filesystem of respective boot mode.

Changes in v8:
* Dropped patch to set_env_default in the env/nowhere driver. Instead used env_relocate in place of env_load which does sets up the default env.
