This is a *partial* revert of "powerpc/85xx: Load all early TLB entries
at once" (d9e1831a420267a7ced708bb259d65b0a3c0344d.)

My dusty old P4080DS just completely fails to boot (no output at all)
without this revert.  I have no clue what's going on here, I just
bisected it down and since it looks like an optimization to me I just
reverted it - and voil=C3=A1, the P4080 boots again.

I'm not subscribed to linuxppc-dev, please keep me in Cc:.  Also I
contribute to the kernel only very rarely and have no clue how to find
out when the appropriate time in the merge window is to submit things to
linuxppc-dev... my apologies.
Don't worry about the timing of sending patches.

Your patch will be tracked in patchwork, so if it's not a good time
we'll just ignore it until it is a good time :)

cheers
