[Skiboot-stable] [git pull] skiboot op940.x

[Vasant Hegde]

Hi Oliver,

Please pull first set of patches for OP940.x branch. This is based on top 
skiboot v6.5.3 and contains
bunch of opencapi related patches which are requested by product team.

Note that this is *not* skiboot stable branch. If anyone wants skiboot stable 
branch they should use v6.5.x.
