[PATCH 1/3] mtd: lpddr: Fix bad logic in print_drs_error

[Gustavo A. R. Silva]

Update logic for broken test. Use a more common logging style.

It appears the logic in this function is broken for the
consecutive tests of

        if (prog_status & 0x3)
                ...
        else if (prog_status & 0x2)
                ...
        else (prog_status & 0x1)
                ...

Likely the first test should be

        if ((prog_status & 0x3) == 0x3)

Found by inspection of include files using printk.
