mtd: rawnand: fsl_elbc: Fix detection when nand_scan_ident() has not selected ecc.mode
ecc.mode is set to 0 (aliased to NAND_ECC_NONE) either when function
nand_scan_ident() has not selected ecc.mode or when it selected it to none
ecc mode.
Distinguish between these two states by checking of node property
"nand-ecc-mode" which function nand_scan_ident() uses for filling ecc.mode.
This change fixes usage of none ecc mode if it is specified in DTS file.
Fixes: c9ea9019c5aa ("mtd: rawnand: fsl_elbc: Use ECC configuration from device tree")
