Steven Slupsky a18a73c19b drivers: wdt: sam0: fix register access in feed() 
The wdt CLEAR register is a write synchronized register.
To avoid bus stall, check the status of SYNCBUSY before
accessing the register.

Use SYNCBUSY register for SAM E.
If the wdt is syncing, return -EAGAIN to avoid bus stall.
