[PATCH v2] board: fsl: lx2160a: Fix the loop in board_fix_fdt function

[Pankaj Bansal]

Fix loop in board_fix_fdt that erroneously increments the counter
in all cases. the counter should be incremented only if a matching
string has been found.

Fixes: 5d535aa40b ("board: fsl: lx2160a: implement board_fix_fdt")

Notes:
    V2:
    - assigned value to i when declared : suggested by Jagdish
    - removed mention of "for loop" from commit header and description
      becuase we have replaced for loop with while loop : suggested by
      Jagdish
