ACPI / platform: Add support for build-in properties
We have a couple of drivers, acpi_apd.c and acpi_lpss.c, that need to pass extra build-in properties to the devices they create. Previously the drivers added those properties to the struct device which is member of the struct acpi_device, but that does not work. Those properties need to be assigned to the struct device of the platform device instead in order for them to become available to the drivers. To fix this, this patch changes acpi_create_platform_device function to take struct property_entry pointer as parameter.
