mtd: rawnand: atmel: Fix potential NULL pointer dereference
There is a potential execution path in which function
of_find_compatible_node() returns NULL. In such a case,
we end up having a NULL pointer dereference when accessing
pointer *nfc_np* in function of_clk_get().
So, we better don't take any chances and fix this by null
checking pointer *nfc_np* before calling of_clk_get().
