MIPS: Lemote 2F: cs5536: mfgpt: depend on !highres

This timer does not support oneshot mode and as such the system remains
in periodic mode and won't support high res timers.
This patch adds a note about this in Kconfig and lets it depend on
!highres so users which want to use high timers don' stuck with this
timer.
