Merge branch 'liquidio-CN23XX-part-2'

Raghu Vatsavayi says:

====================
liquidio CN23XX support

I am posting the remaining half of patchset after the
acceptance of first half. With this patchset I am able
to completely submit the code of V3 patchset  which you
earlier advised me to split into smaller ones.

This V5 patch also addresses all the comments from previous
submission:
1) Avoid busy loop while reading registers.
2) Other minor comments about debug messages and constants.

Please apply patches in following order as some of the
patches depend on earlier patches.
