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

feat(spmc): enable handling of the NS bit

In FF-A v1.1 the NS bit is used by the SPMC to specify the
security state of a memory region retrieved by a SP.

Enable the SPMC to set the bit for v1.1 callers or v1.0
callers that explicitly request the usage via FFA_FEATURES.

In this implementation the sender of the memory region must
reside in the normal world and the SPMC does not support
changing the security state of memory regions therefore
always set the NS bit if required by the caller.

feat(spmc): add support for v1.1 FF-A boot protocol

A partition can request the use of the FF-A boot protocol via
an entry in its manifest along with the register (0-3)
that should be populated with a pointer to a data structure
containing boot related information. Currently the boot
information consists of an allocated memory region
containing the SP's manifest, allowing it to map and parse
any extra information as required.

This implementation only supports the v1.1 data structures
and will return an error if a v1.0 client requests the usage
of the protocol.
