Instead of hardcoding -lssl -lcrypto as the flags needed to build
mkimage with FIT signature enabled, use pkg-config when
available. This allows to properly support cases where static linking
is used, which requires linking with -lz, since OpenSSL uses zlib

We gracefully fallback on the previous behavior of hardcoding -lssl
-lcrypto if pkg-config is not available or fails with an error.

The ARM Trusted Firmware or other security solutions are
eating memory from the top of the physical SDRAM1 space,
moving backward from 0xffffffff, currently occupying e.g.
0xfe000000-0xffffffff with Trusted Firmware.
This solution to reserving memory for secure world is not
optimal, so we need to think of how the secure world and
earlier boot stages should communicate to U-Boot what
memory they are eating up. For now let's just put 16MB
aside.
Also enable the memory test command and define start and
end of the test range so we can check that we actually have
all that memory available and working.
