[ARM] pxa: fix PXA27x resume

Browse source

When PXA27x wakes up, tick_resume_oneshot() tries to set a timer
interrupt to occur immediately.  Since PXA27x requires at least
MIN_OSCR_DELTA, this causes us to flag an error.

tick_program_event() then increments the next event time by
min_delta_ns.  However, by the time we get back to programming
the next event, the OSCR has incremented such that we fail again.
We repeatedly retry, but the OSCR is too fast for us - we never
catch up, so we never break out of the loop - resulting in us
never apparantly resuming.

Fix this by doubling min_delta_ns.
