Alexander Boettcher fc6bcd9f9f NOVA: update to latest kernel revision 
The Demo of 64bit Genode/NOVA fails during the booting phase when
physical memory was tried to be mapped lying above 4G boundary.
(qemu -m 4096 triggered it on some systems). The memory never got
mapped and the attempt to access the virtual region resulted
in a unexpected page fault inside Genode core.

The latest revision removed the artificial boundary of 4G for 64bit.

Example trace showing the issue:
([-1] lines show debugging output that mapping failed)
