arm-trusted-firmware-mvebu: add cryptopp

Based on the Build Instructions for Trusted-Firmware-A [1],
there is a required cryptopp [2].

In the past, it used 'tbb_linux' image tool binary, which seems to
be buggy, deprecated and removed from A3700-utils-marvell and it should
not be used anymore. That's why I removed 001-imagetool.patch, which is
no longer necessary.
