Calling ida_alloc earlier in rproc_alloc ensures that the rproc->index is
properly set.

Hello Bjorn,
Gentle reminder.
I would need that we clarify pending points with this commit and [3/8] to move

When a resource table is loaded by an external entity such as U-boot or
OP-TEE, we do not necessarily get the device address(da) but the physical
address(pa).
This helper performs similar translation than the rproc_da_to_va()
but based on a physical address.

Updates vs previous version:
- remove the rproc:load_fw() ops introduced in previous version
- remove duplicate call of rproc_release_fw in rproc_fw_boot and
to request the TEE application to perform actions
to return to the initial state on stop or on error during the boot
sequence.
