binaries-marvell: new package

Some systems, including Marvell Armada 7k/8k SoCs, have a separate
System Control Processor (SCP) for power management, clocks, reset
and system control. ATF Boot Loader stage 2 (BL2) loads optional
SCP_BL2 image into a platform-specific region of secure memory.

This package adds SCP_BL2 firmware for Marvell Armada 7040 and 8040 SoCs.
