feat(lfa): introduce support for call_again for LFA_PRIME

LFA_PRIME is a single-threaded operation that is not pinned to
a specific CPU. The implementation must support calls being
issued from different CPUs, even for several calls to prime the
same component.

This patch checks if the plat_lfa_load_auth_image return -EAGAIN
indicating that the platform expects the LFA_PRIME call to be
issued again. This is done by returning LFA_SUCCESS and setting
flags[0] to 1, indicating that LFA_PRIME is incomplete and must
be called again.

feat(lfa): allow LFA_PRIME from one CPU at a time

LFA_PRIME is a single-threaded operation that is not pinned
to a specific CPU. The implementation must support calls being
issued from different CPUs, even for several calls to prime
the same component. However, those calls must not happen
concurrently.

This patch introduces a spinlock across the LFA_PRIME call to
support this requirement. In case of concurrent calls, the
LFA_BUSY error code is returned to the caller.

fix(el3-spmc): validate fragment offset

Per Table 4.3 of DEN 0140 1.3ALP0, the fragment offset passed to
FFA_MEM_FRAG_RX has the following requirement:

Offset must be equal to one of the following:
– The number of bytes of the transaction descriptor
transmitted prior to the invocation of this
interface.
– The offset used in the previous invocation of this
interface. This allows the Sender to re-transmit
the previous fragment if the Receiver could not
receive it due to an IMPLEMENTATION DEFINED
reason.

Keep track of the last and next fragment offsets between calls
to FFA_MEM_RETRIEVE_REQ and FFA_MEM_FRAG_RX and validate the
fragment offset, returning INVALID_PARAMETERS if it doesn't match
one of the two expected values.

BREAKING CHANGE: no longer accepts invalid fragment offsets

perf(spmd): don't initialise context on boot, do it on CPU_ON

Normal and Realm worlds setup their contexts whenever a core comes
online. This speeds up boot and as a side effect allows any cores that
are never turned on to not be initialised.

So do this for spmd's Secure world too. This makes all three worlds
consistent.
