This reverts the patch https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/5313 due to a timing issue with the merge. The merge occurred at the same time as the additional comments and thusly were were not seen until the merge was done. This reverts the change and additional patches from Alexei will follow to address the concerns expressed in the orignal patch.

Define SPMD PM hooks for warm boot and off events. svc_on_finish handler
enters the SPMC at the entry point defined by the secondary EP register
service. The svc_off handler notifies the SPMC that a physical core is
being turned off through a notification message.

SPMD: handle SPMC message to register secondary core entry point

Upon booting, the SPMC running on the primary core shall register the
secondary core entry points to which a given secondary core being woken
up shall jump to into the SPMC . The current implementation assumes the
SPMC calls a registering service implemented in the SPMD for each core
identified by its MPIDR. This can typically happen in a simple loop
implemented in the early SPMC initialization routines by passing each
core identifier associated with an entry point address and context
information.
This service is implemented on top of a more generic SPMC<=>SPMD
interface using direct request/response message passing as defined by
the FF-A specification.
