[ARM] pxa: remove boot time RTC initialisation

The RTC library code contains everything necessary to set the
system time from the RTC; for similar reasons as the previous
commit, it's far better to let the RTC library code sort this
out rather than implement something which might not be
appropriate for everyone.
