ACPICA: Update RSDP table definitions.
This patch updates RSDP table header definitions as such enhancement has been made in ACPICA upstream already. It ports that change to the Linux source to reduce source code differences between Linux and ACPICA upstream. This patch does not affect the generation of the Linux kernel binary.
