[avr-libc-dev] correction in xmega wdt_enable/ wdt_enable

[S, Pitchumani]

Hi,

As per datasheet, wdt_enable should wait until SYNCBUSY bit in STATUS register 
is cleared.
Also the wdt_disable macro is not present for xmega.

Attached patch corrects update wdt_enable macro and adds wdt_disable macro for 
xmega devices.

Please review and send your comments.

Pitchumani
