ACPI: Move device resources interpretation code from PNP to ACPI core

Browse Source 
Move some code used for parsing ACPI device resources from the PNP
subsystem to the ACPI core, so that other bus types (platform, SPI,
I2C) can use the same routines for parsing resources in a consistent
way, without duplicating code.
