    x86: Fix parse_reservetop() build failure on certain configs

    Commit e67a807 ("x86: Fix 'reservetop=' functionality") added a
    fixup_early_ioremap() call to parse_reservetop() and declared it
    in io.h.

    But asm/io.h was only included indirectly - and on some configs
    not at all, causing a build failure on those configs.
