Subject: [PATCH 4/8] dt-bindings: nvmem: sfp: Add compatible binding for TA 2.1 SFPs

Trust Architecture (TA) 2.1 devices include the LS1012A, LS1021A,
LS1043A, and LS1046A. The SFP device on TA 2.1 devices is very similar
to the SFP on TA 3.0 devices. The primary difference is a few fields in
the control register. Add a compatible string.
