In the quest to remove all stack VLA usage from the kernel[1], this
replaces struct crypto_skcipher and SKCIPHER_REQUEST_ON_STACK() usage
with struct crypto_sync_skcipher and SYNC_SKCIPHER_REQUEST_ON_STACK(),
which uses a fixed stack size.

OMAP AES hw supports AES-GCM mode. This patch adds support for GCM and
RFC4106 GCM mode in omap-aes driver. The GCM implementation is mostly
written into its own source file, which gets built into the same driver
binary as the existing AES support.

Move over most of the omap-aes driver internal definitions to a separate
header file. This is done so that the same definitions can be used in
the upcoming AES-GCM support code.
