boards: nxp: Remove old LPSPI timing properties

The old controller based timing properties being present in boards DTS
is making it so that overlays cannot specify timing parameters of spi
devices, because the old controller properties take precedence in the
driver still. We should remove these anyways, so first step is to remove
from board level, luckily there is only these two cases.
