mtd: rawnand: Pass the CS line to be selected in struct nand_operation
In order to deprecate the ->select_chip hook we need to pass the CS
line a NAND operations are targeting. This is done through the
addition of a cs field to the nand_operation struct.
We also need to keep track of the currently selected target to
properly initialize op->cs, hence the ->cur_cs field addition to the
nand_chip struct.
Note that op->cs is not assigned in nand_exec_op() because we might
rework the way we execute NAND operations in the future (adopt a
queuing mechanism instead of the serialization we have right now).
