use XOSC1 directly for DPLL1

DPLL1 can take directly XOSC1 as input and divide it to 2 MHz.
thus the intermediate GCLK11 is not needed.
we now also completely de-configure GCLK11
this configuration is not supported by Atmel START since it does
not know about the division and thinks the input frequency
exceeds the maximum
GCLK2 is also disabled for now because it is not used
