[PATCH v2 00/13] Enable Virtual Console Concentrator (VCC)

[Jag Raman]

Patchset to enable Virtual Console Concentrator (VCC). VCC provides
access to the serial console of a guest domain. It creates a RAW
VIO/LDC link between the guest domain & primary through which serial
console data is shared.

This set addresses feedback provided by Dave Miller. Cleanup of
driver state is also addressed in this set. Patches updated
are 4, 5, 6 & 7.

version3:
 - PATCH 04/13: delete VIO timer during removal
 - PATCH 05/13: remove sysfs attr group during cleanup
 - PATCH 06/13: Timer access macros replaced with direct
                access. Timer routines check if VCC is
                removed. Delete timer during cleanup
 - PATCH 07/13: avoid explicit typecast of void pointer
