mtd: rawnand: rockchip: ensure NVDDR timings are rejected

Browse source 
commit b27d8946b5 upstream.

.setup_interface first gets called with a "target" value of
NAND_DATA_IFACE_CHECK_ONLY, in which case an error is expected
if the controller driver does not support the timing mode (NVDDR).

Fixes: a9ecc8c814 ("mtd: rawnand: Choose the best timings, NV-DDR included")
