mtd: rawnand: marvell: ensure timing values are written

Browse Source 
[ Upstream commit 8a6f4d346f3bad9c68b4a87701eb3f7978542d57 ]

When new timing values are calculated in marvell_nfc_setup_interface()
ensure that they will be applied in marvell_nfc_select_target() by
clearing the selected_chip pointer.
