mtd: nand: allow to set only one of ECC size and ECC strength from DT
Currently, it is valid to specify both "nand-ecc-step-size" and
"nand-ecc-strength", but not allowed to set only one of them.
This requirement has a conflict with "nand-ecc-maximize"; this flag
is used when you want the driver to choose the best ECC strength.
If "nand-ecc-maximize" is set, "nand-ecc-strength" is very likely to
be unset.
It would be possible to make the if-conditional more complex by
adding the check for the NAND_ECC_MAXIMIZE flag, but I chose to drop
the check entirely. I thought of the situation where the hardware
has a fixed ECC step size (so it can be hard-coded in the driver),
whereas the ECC strength is configurable by software. In that case,
we may want to only set "nand-ecc-strength" (or "nand-ecc-maximize")
in DT.
