This saves a lot of flash space, in case functions from libtomcrypt
are not used (currently only RSA related).
When RSA is not used, the linker can now drop all libtomcrypt related things.
This is especially relevant for bootloaders using the SW crypto.

Use the same memory allocation in sw_crypto driver as what is used in
src/lib/crypto libraries
In addition, in nuttx protected build, allocate all memory from kernel heap

This is more logical place for the "backend" implementation than
directly under platform.
This also allows making other implementations as "real" drivers, as well as proper configuration via Kconfigs
