x86: avoid remapping data in parse_setup_data()
commit 30e46b574a1db7d14404e52dca8e1aa5f5155fd2 upstream. Type SETUP_PCI, added by setup_efi_pci(), may advertise a ROM size larger than early_memremap() is able to handle, which is currently limited to 256kB. If this occurs it leads to a NULL dereference in parse_setup_data(). To avoid this, remap the setup_data header and allow parsing functions for individual types to handle their own data remapping.
