clocksource: fix compilation if no GENERIC_TIME

Browse Source 
commit a362c638bd upstream

Commit a9238ce3bb 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 the implementation of clocksource_max_deferment() also for
such platforms.
