mtd: lpddr: Fix bad logic in print_drs_error

commit 1c9c02bb22684f6949d2e7ddc0a3ff364fd5a6fc upstream.

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.

Fixes: eb3db275
