lantiq: kernel: xway-nand: Move ECC engine setting to new DT binding
When trying to add support for another device with Micron NAND chips, it was discovered that the default setting in the kernel source does not work with Micron Chips, since the device trees setting is overwritten and hard coded by the kernel xway_nand driver. This was the original reason for this PR. A kernel patch sets the default ECC mode to soft without overwriting the device tree settings and the device tree for devices using it are updated with new parameters because the old ones are deprecated by torvalds/linux@533af69. A patch for kernel 5.4 is provided to support the new settings because kernel 5.4 does not support it. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de>
