Just a quick patch to trace tlbie(l)'s. The idea being that it can be
enabled when we suspect corruption or when we need to see if we are doing
the right thing during flush. I think the format can be enhanced to
make it nicer (expand the RB/RS/IS/L cases in more detail if we ever
need that level of details).

A typical trace might look like this

<...>-5141  [062]  1354.486693: tlbie:
	tlbie with lpid 0, local 0, rb=7b5d0ff874f11f1, rs=0, ric=0 prs=0 r=0
systemd-udevd-2584  [018]  1354.486772: tlbie:
	tlbie with lpid 0, local 0, rb=17be1f421adc10c1, rs=0, ric=0 prs=0 r=0
...

qemu-system-ppc-5371  [016]  1412.369519: tlbie:
	tlbie with lpid 0, local 1, rb=67bd8900174c11c1, rs=0, ric=0 prs=0 r=0
