crypto: ccp - Add support for valid authsize values less than 16
commit 9f00baf74e4b6f79a3a3dfab44fb7bb2e797b551 upstream.
AES GCM encryption allows for authsize values of 4, 8, and 12-16 bytes.
Validate the requested authsize, and retain it to save in the request
context.
Fixes: 36cf515b9bbe2 ("crypto: ccp - Enable support for AES GCM on v5 CCPs")
