Subject: crypto: caam - Add support for i.MX8M Mini
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 112e7b7b6a2e33fbc5624991694d4a630f99e04e
Patch-mainline: v5.6-rc1
References: jsc#SLE-16106

The i.MX8M Mini uses the same crypto engine as the i.MX8MQ, but
the driver is restricting the check to just the i.MX8MQ.

This patch expands the check for either i.MX8MQ or i.MX8MM.
