MLK-9769-14 Add CRYPTO_ALG_KERN_DRIVER_ONLY flag to Freescale CAAM driver

The CRYPTO_ALG_KERN_DRIVER_ONLY flag is used to indicate that
the crypto algorithm is only available via a kernel driver.
This patch adds the flag only when the flag is available in the
kernel.  Utilizing the flag based on it's availability in the
kernel allows the driver to compile on older kernel versions.

The original community patch is located at
http://permalink.gmane.org/gmane.linux.kernel.cryptoapi/6547
for reference.
