rsa: add support for 4096 and 8192 bit keys
Allow to use larger RSA keys by setting CONFIG_RSA_KEY_SIZE to 4096 or
8192 rather than using the default 2048-bit size.
It's mainly for benchmarking purpose right now as we don't have the RAM
to store the 3x key size buffer and the flash space for the public key
structure.

BRANCH=samus
BUG=none
TEST=build Zinger with CONFIG_RSA_KEY_SIZE equals to 4096 and run it.
