sio/nuvoton/npcd378: Fix ACPI errors

In commit 0a0945c6a211 (sio/nuvoton/npcd378: Use acpi_device_path_join),
some oversights were made. Instances of "strconcat(scope, ..." should be
replaced with "..._join(dev->bus->dev, ..." instead of "..._join(dev, ...".

On HP 8200 USDT, this fixes ACPI error like this on resume from S3:
    ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.LPCB.SIO0.L040.RMFG], AE_NOT_FOUND (20230628/psargs-330)
    ACPI Error: Aborting method \_GPE._L08 due to previous error (AE_NOT_FOUND) (20230628/psparse-529)
    ACPI Error: AE_NOT_FOUND, while evaluating GPE method [_L08] (20230628/evgpe-511)

RMFG seems to be a typo of PMFG made in that same commit.
