x86/boot: Mostly revert commit ae7e1238 ("Add ACPI RSDP address to setup_header")
Peter Anvin pointed out that commit: ae7e1238 ("x86/boot: Add ACPI RSDP address to setup_header") should be reverted as setup_header should only contain items set by the legacy BIOS. So revert said commit. Instead of fully reverting the dependent commit of: e7b66d16 ("x86/acpi, x86/boot: Take RSDP address for boot params if available") just remove the setup_header reference in order to replace it by a boot_params in a followup patch.
