Add S-EL1 interrupt handling support in the TSPD

This patch adds support in the TSPD for registering a handler for
S-EL1 interrupts. This handler ferries the interrupts generated in the
non-secure state to the TSP at 'tsp_fiq_entry'. Support has been added
to the smc handler to resume execution in the non-secure state once
interrupt handling has been completed by the TSP.

There is also support for resuming execution in the normal world if
the TSP receives a EL3 interrupt. This code is currently unused.
