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 } } }) Change-Id: Iab33182a5f64c89151966f5e79f4f7c30840c46f Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15514 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
