Up to now the pasemi nand driver only supported a single device
instance. However the check for that was racy because two parallel calls
of pasemi_nand_probe() could pass the check
if (pasemi_nand_mtd)
return -ENODEV;
before any of them assigns a non-NULL value to it.
So rework the driver to make use of per-device driver data.
As an intended side effect the driver can bind more than one device and
also gets rid of the check
if (!pasemi_nand_mtd)
return 0;
in the remove callback that could only ever trigger after the above race
happened.
