[ACPI]
- Fix AcpiRegQueryValue, to allow querying the required buffer size only (which was already used, but just didn't work) - Fix GetProcessorInformation. Previously the function failed at the start, but no one checked the return value. Check return values of called functions, and properly NULL-Terminate the components of the REG_MULTI_SZ style value that ProcessorHardwareIds is supposed to be. - Fix NULL-termination in Bus_PDO_QueryDeviceId as well as clean up the code, fix indentation and broken if/else cases - Add some ASSERTs and comments svn path=/trunk/; revision=61666
