Subject: efi/capsule-loader: Explicitly include linux/io.h for page_to_phys()
Patch-mainline: v5.6-rc1
Git-commit: c6625a314cb81149718390c6be01a9294a016966
References: jsc#SLE-16407

Through a labyrinthian sequence of includes, usage of page_to_phys() is
dependent on the include of asm/io.h in x86's asm/realmode.h, which is
included in x86's asm/acpi.h and thus by linux/acpi.h.  Explicitly
include linux/io.h to break the dependency on realmode.h so that a
future patch can remove the realmode.h include from acpi.h without
breaking the build.
