dt-bindings: mtd: Document boolean NAND ECC properties
Document nand-use-soft-ecc-engine and nand-no-ecc-engine properties.
The former is here to force software correction, the latter prevents
any correction to happen.
These properties (along with nand-ecc-engine) are supposed to be more
accurate than the current nand-ecc-modes wich is very misleading and
very often people think it is mandatory while the core should be
relied upon to decide which correction to handle.
nand-ecc-mode was already inacurate, but it becomes totally
problematic with setups where there are several hardware engines.
