ARM: dts: at91: sam9x60ek: Enable qspi node 

The sam9x60 qspi controller uses 2 clocks, one for the peripheral register
access, the other for the qspi core and phy. Both are mandatory.

Enable the qspi node together with the SST26VF064B qspi nor flash
memory. Booting from the QSPI NOR flash is now possible.
