By default on P9, the HW CAM line (23bits) is hardwired to :
0x000||0b1||4Bit chip number||7Bit Thread number.
When the block group mode is enabled at the controller level (PowerNV),
the CAM line is changed for CAM compares to :
4Bit chip number||0x001||7Bit Thread number
This will require changes in xive_presenter_tctx_match() possibly.
This is a lowlevel functionality of the HW controller and it is not
strictly needed. Leave it for later.
