ACPI: SPCR: Use access width to determine mmio usage The current SPCR code does not check the access width of the MMIO, and uses a default of 8bit register accesses. This prevents devices that only do 16 or 32bit register accesses from working. By simply checking this field and setting the MMIO string appropriately, this issue can be corrected. To prevent any legacy issues, the code will default to 8bit accesses if the value is anything but 16 or 32.
