avr32: move NODES_SHIFT into Kconfig and delete numnodes.h

This patch moves the NODES_SHIFT symbol into Kconfig to synchronize AVR32
architecture with the current kernel. The global header files do longer use the
value from numnodes.h.

See commit c80d79d746cc48bd94b0ce4f6d4f3c90cd403aaf for details.
