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. Signed-off-by: Vincent Palatin <vpalatin@chromium.org> BRANCH=samus BUG=none TEST=build Zinger with CONFIG_RSA_KEY_SIZE equals to 4096 and run it.
