drivers/generic/max98357a: Fix naming and ACPI path handling

The upstream kernel driver is not using the of-style naming for
    sdmode-gpio so remove the maxim prefix, and remove the duplicate
    entry for the sdmode-delay value as well.

Also fix the usage of the path variable, since the device path uses
    a static variable it can't be assigned that early or it will be
    overwritten by later calls.

This results in the following output for the _DSD when tested on
    reef mainboard:

Name (_DSD, Package (0x02)
    {
        ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301")
        Package (0x02)
        {
            Package (0x02)
            {
                "sdmode-gpio",
                Package (0x04)
                {
                    _SB.PCI0.HDAS.MAXM,
                    Zero,
                    Zero,
                    Zero
                }
            },
            Package (0x02)
            {
                "sdmode-delay",
                Zero
            }
        }
    })
