Space after the '=' please.

If at all possible, your bootloader should set CNTFREQ, and
clock-frequency should only be used as a last resort when it's
impossible to get it to set CNTFREQ. It's not possible to set CNTFREQ
from the non-secure side, so guests (which might not be Linux, and might
not handle DT in the same way) may see a completely wrong frequency
value.

Thanks,
Mark.
