Kees Cook e87f203ce6 crypto: omap-aes - Remove VLA usage of skcipher
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.

Tero Kristo ad18cc9d0f crypto: omap-aes - Add support for GCM mode
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.

Tero Kristo 5b3d4d2e61 crypto: omap-aes - move definitions over to a separate header file
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.
