Sean Anderson	33a1c66186	nvmem: sfp: Add support for TA 2.1 devices ... This adds support for Trust Architecture (TA) 2.1 devices to the SFP driver. There are few differences between TA 2.1 and TA 3.0, especially for read-only support, so just re-use the existing data.

Sean Anderson	943eadbdb1	nvmem: sfp: Use regmap ... This converts the SFP driver to use regmap. This will allow easily supporting devices with different endians. We disallow byte-level access, as regmap_bulk_read doesn't support it (and it's unclear what the correct result would be when we have an endianness difference).
