x86/boot: Mostly revert commit ae7e1238e6 ("Add ACPI RSDP address to setup_header")

Browse Source 
Peter Anvin pointed out that commit:

  ae7e1238e6 ("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:

  e7b66d16fe ("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.
