Subject: [PATCH v1 2/2] caam: imx8m: change to use of_match_node in run_descriptor_deco0

From: Alice Guo <alice.guo@....com>

Patch "fix the built-in caam driver cannot match soc_id" provides
imx8m_machine_match to match i.MX8M{Q,M,N,P}, so change to use to
of_match_node which can simplify the code.
