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.

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).
