avr32: Use board_postclk_init instead of gclk_init
Replace the avr32-specific gclk_init() board hook with the standard
board_postclk_init() hook which is supposed to run at the same point
during initialization.
Provide a dummy weak alias for boards not implementing this hook. The
cost of this is:
- 2 bytes for the dummy function (retal 0)
- 2 bytes for each unnecessary function call (short rcall)
which is a pretty small price to pay for avoiding lots of #ifdef
clutter. In this particular case, all boards probably end up slightly
smaller because we avoid the conditional checking if the gclk_init
symbol is NULL.
