ACPI: Introduce acpi_unload_parent_table() usages in Linux kernel
ACPICA has implemented acpi_unload_parent_table() which can exactly replace the acpi_get_id()/acpi_unload_table_id() implemented in Linux kernel. The acpi_unload_parent_table() has been unit tested in ACPICA simulation environment. This patch can also help to reduce the source code differences between Linux and ACPICA.
