firmware/dmi_scan: generalize for use by other archs
This patch makes a couple of changes to the SMBIOS/DMI scanning code so it can be used on other archs (such as ARM and arm64): (a) wrap the calls to ioremap()/iounmap(), this allows the use of a flavor of ioremap() more suitable for random unaligned access; (b) allow the non-EFI fallback probe into hardcoded physical address 0xF0000 to be disabled.
