Subject: crypto: ghash-generic - move common definitions to a new header file

From: Marcelo Cerri <marcelo.cerri@canonical.com>

commit a397ba829d7f8aff4c90af3704573a28ccd61a59 upstream.

Move common values and types used by ghash-generic to a new header file
so drivers can directly use ghash-generic as a fallback implementation.

Fixes: cc333cd68dfa ("crypto: vmx - Adding GHASH routines for VMX module")
