robert-hh 05bb26010e samd: Always provide the machine.RTC class.
Even if boards do not have a clock crystal.  In that case, the clock
quality will be very poor.

Always having machine.RTC means that the date/time can be set in a way that
is consistent with other ports.

This commit also removes the special code in modutime.c for devices without
the RTC class.
