[RFC Patch 09/19] ACPI: Fix a bug in parsing ACPI Memroy24 resource

[Jiang Liu]

According to ACPI spec 5, section 6.4.3.1 "24-Bit Memory Range Descriptor",
minimum, maximum and address_length field in struct acpi_resource_memory24
is in granularity of 256-bytes. So shift 8-bit left to get correct address.
