ACPI: utils: introduce acpi_get_local_u64_address()

Browse source

The ACPI _ADR is a 64-bit value. We changed the definitions in commit
ca6f998cf9 ("ACPI: bus: change _ADR representation to 64 bits") but
some helpers still assume the value is a 32-bit value.

This patch adds a new helper to extract the full 64-bits. The existing
32-bit helper is kept for backwards-compatibility and cases where the
_ADR is known to fit in a 32-bit value.
