PNP / ACPI: Use ACPI_COMPANION_SET() during initialization

Browse Source 
pnpacpi_add_device() calls acpi_bind_one() on an already registered
device, which is a mistake, but it can initialize the ACPI companion
field of the struct device to be registered using ACPI_COMPANION_SET()
instead, so make it do that.
