[GIT PULL] FSI updates round 2 for 4.19

[Benjamin Herrenschmidt]

Hi Greg !

This is the second round of updates of the FSI stack.

These comprise of:

 - Some build fixes detected with COMPILE_TEST when
used on "other" archs

 - Sparse warning fixes

 - Some object lifetime fixes

 - A new feature to control some of the protocol delays

 - Overheaul of the "SCOM" driver used to access the POWER
processor internal SCOM bus.

 - Preparatory work for the new ColdFire coprocessor based FSI master
work which, along some other newer work is still going through the last
few rounds of polish and DT bindings reviews.

The following changes since commit 9f4a8a2d7f9d71093f41c4bb0ef8707e8145bad3:

  fsi/sbefifo: Add driver for the SBE FIFO (2018-06-12 14:05:39 +1000)
