    resources: introduce reserved_ram_resource()
    mmio_resource() was previously being used for reserving
    RAM from the OS by using IORESOURCE_IGNORE_MTRR atrribute.
    Instead, be more explicit for those uses with
    reserved_ram_resource(). bad_ram_resource() now calls
    reserved_ram_resource(). Those resources are marked as cacheable
    but reserved.
    The sandybridge and haswell code were relying on the implementation
    fo the MTRR algorithm's interaction for reserved regions. Instead
    be explicit about what ranges are MMIO reserved and what are RAM
