The device-tree booted MMP2 needs to enable the timer clock, otherwise
it would stop ticking when the boot finishes.

It can also use the clock rate from the clk, the non-DT boards need to
keep using the hardcoded rates.

While I agree this is good idea for mainline (thus my ack), I don't
think it is suitable for stable, as older kernels will not run on OLPC
in useful way, anyway.

Interesting, so OLPC doesn't run on 4.20?
