clocksource/drivers/dbx500: Demote dbx500 PRCMU clocksource
Demote the DBx500 PRCMU clocksource to quality 100 and mark it as NONSTOP so it will still be used for timekeeping across suspend/resume. The Nomadik MTU timer which has higher precision will be used when the system is up and running, thanks to the recent changes properly utilizing the suspend clocksources. This was discussed back in 2011 when the driver was written, but the infrastructure was not available upstream to use this timer properly. Now the infrastructure is there, so let's finalize the work.
