Two helpers have been added to the core to do all kind of controller
side configuration/initialization between the detection phase and the
final NAND scan. Implement these hooks so that we can convert the driver
to just use nand_scan() instead of the nand_scan_ident() +
nand_scan_tail() pair.

Prepare the migration to nand_scan() by moving both calls to
nand_scan_ident() and nand_scan_tail() in a single spot.

An error after nand_scan_tail() should trigger a nand_cleanup(), not a
nand_release() as mtd_device_register() (or one of its variants) has not
been called and there is no need to deregister any MTD device yet.

GPIO consumers should no longer include <linux/gpio.h>, and instead
include <linux/gpio/consumer.h>.
Also, explicitly include <include/io.h> since it seems to be missing
after switching to <linux/gpio/consumer.h>.
This fixes a build error when selecting the driver without selecting
GPIOLIB, which can happen when COMPILE_TEST=y.

In jz_nand_detect_bank(), chipnr is a size_t argument. Use %zu instead
of %i when printing it.

As part of the process of sharing more code between different NAND
based devices, we need to move all raw NAND related code to the raw/
