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
}
}
})
