Now that all drivers go through nand_set_flash_node() to parse the generic
NAND properties, we can move all of_get_nand_xxx() helpers in to
nand_base.c, make them static and remove of_mtd.c and of_mtd.h.

NAND subsystem is being slightly reworked to store ECC details in
separated fields. In future we'll want to add support for more DT
properties as specifying every possible setup with a single
"nand-ecc-mode" is a pretty bad idea.
To allow this let's add a helper that will support something like
"nand-ecc-algo" in future. Right now we use it for keeping backward
compatibility.

This commit adds simple helpers to obtain the devicetree properties
that specify the ECC strength and ECC step size to use on a given
NAND controller.

It seems the include guard was copied from of_net.h.

Just like the rest of the subsystems, let's add the required no-op
functions to implement stubs when CONFIG_OF=n.
This prevents MTD drivers from having ugly ifdefs in their code,
and instead hide the ifdef monster in the header closet (far away
from people's sight).

This patch does the following:
-const int of_get_nand_ecc_mode(struct device_node *np)
+int of_get_nand_ecc_mode(struct device_node *np)
because:
1. it is probably just a typo?
2. it causes warnings like this when people assing the returned
value to an 'int' variable:
include/linux/of_mtd.h:14:18: warning: type qualifiers ignored on functi=
on return type [-Wignored-qualifiers]
Remove also the unnecessary "extern" qualifier to be consistent with other
declarations in this file.

- nand-ecc-mode : String, operation mode of the NAND ecc mode.
Supported values are: "none", "soft", "hw", "hw_syndrome", "hw_oob_first",
"soft_bch".
- nand-bus-width : 8 or 16 bus width if not present 8
- nand-on-flash-bbt: boolean to enable on flash bbt option if not present false
