[PATCH v2 0/3] arm: layerscape: Add sfp driver

[Sean Anderson]

This adds a driver for the Security Fuse Processor (SFP). It only
supports Trust Architecture (TA) 2.1 SFPs, but it should be fairly
trivial to add support for TA 3.1 SFPs. See [1] for Linux
bindings/driver support.

Changes in v2:
- Use the sfp clock directly, instead of assuming we get the platform
  clock. This corresponds better to what other drivers on these devices
  do.
- Rename clock to "sfp" to be more descriptive.
- update the clockgen node for ls1021a
