mx31ads: fix 32kHz clock handling

Browse Source 
According to schematics and to RedBoot sources, the MX31ADS uses a 32768Hz
oscillator as a SKIL source. Fix previously wrongly assumed 32000Hz value.
Also fix a typo when verifying a jumper configuration. While at it, make
two needlessly global functions static.
