[PATCH -stable 2.6.32.7] clocksource: fix compilation if no GENERIC_TIME

[Aaro Koskinen]

Commit a9238ce3bb0fda6e760780b702c6cbd3793087d3 broke compilation on
platforms that do not implement GENERIC_TIME (e.g. iop32x):

  kernel/time/clocksource.c: In function 'clocksource_register':
  kernel/time/clocksource.c:556: error: implicit declaration of function 'clocksource_max_deferment'

Provide a dummy implementation of clocksource_max_deferment() for such
platforms.
