The driver calls devm_kzalloc()/devm_kfree() to allocate/free memory.
They are declared in <linux/device.h>, not in <linux/slab.h>.

The denali_dt_probe() calls clk_disable_unprepare() in the bailout
path, whereas denali_dt_remove calls clk_disable(), inconsistently.
Replace the latter with clk_disable_unprepare() to make sure to
unprepare the clock.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

Use devm_ioremap_resource() in order to make the code
simpler, and remove redundant return value check of
platform_get_resource_byname() because the value is
checked by devm_ioremap_resource().

Since this driver is dt only and denali_nand_dt_ids is always
compiled in, use of of_match_ptr() macro is not necessary.

platform_get_irq() also returns -ENXIO upon failure.
Use it instead of hardcoded return type.
Fixes the following smatch warning:
drivers/mtd/nand/denali_dt.c:93 denali_dt_probe() info:
why not propagate 'denali->irq' from platform_get_irq() instead of (-6)?

module_platform_driver() removes some boilerplate and makes the code

The return value of devm_ioremap_nocache should be checked here instead
of res.

Add a device tree version of the Denali NAND driver. Based
on an original patch from Jamie Iles to add a MMIO version
of this driver.
