mtd: OneNAND: Introduce chip_probe function
Samsung SoCs use the own OneNAND controler and detect OneNAND chip at power on. To use this feature, introduce the chip_probe function. Also remove workaround for Samsung SoCs. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
