[PATCH V2 0/4] mtd: nand: add enum nand_ecc_algo

Some time ago I started working on a new "nand-ecc-algo" property to allow
specifying ECC algorithm for hardware ECC mode as well.
Boris pointed out it's becoming a bit messy that way as we already have value
NAND_ECC_SOFT_BCH.
I suggested deprecating "soft_bch" value from nand-ecc-mode property and got
Boris agreed and no objections from others. So there is how I want to implement
this.
If you agree on this way & apply my patches, I'll start modifying NAND drivers
(similarly to the nandsim) and then will try to drop NAND_ECC_SOFT_BCH except
for handling backward compatibility.
Then finally we should be able to add "nand-ecc-algo" property support properly.

V2: Add of_get_nand_ecc_algo helper (in 2/4) instead of this slightly hacky code
    in nand_dt_init that would be replaced anyway.
