ppc/85xx: Add tracking of TLB CAM usage
We need to track which TLB CAM entries are used to allow us to "dynamically" allocate entries later in the code. For example the SPD DDR code today hard codes which TLB entries it uses. We can now make that pick entries that are free. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
