QCOM NAND controller supports only one step size (512) so
nand-ecc-step-size DT property is redundant. This property
can be removed and ecc step size can be assigned with 512 value.

* Changes from v3:

 1. Minor change in comment
    (s/512 bytes of data in each step/512 bytes data steps)

* Changes from v2:

 NEW CHANGE

  1. Removed the custom logic and used the helper fuction.
