Notice that the bit_width, bit_offset and access_width fields in struct acpi_generic_address are not used during GPE register accesses any more, so introduce a simplified address structure type, struct acpi_gpe_address, to represent addresses of GPE registers and use it instead of struct acpi_generic_address in struct acpi_gpe_register_info.
