ACPI: Define acpi_put_table cleanup handler and acpi_get_table_pointer() helper

Browse source

Define a cleanup helper for use with __free to release the acpi table when
the pointer goes out of scope. Also, introduce the helper
acpi_get_table_pointer() to simplify a commonly used pattern involving
acpi_get_table().

These are first used in a subsequent commit.
