memhp: don't generate memory hotplug AML if it's not enabled/supported
That reduces DSDT by 910 bytes when memory hotplug isn't enabled. While doing so drop intermediate variables/arguments passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making it local to memory_hotplug.c, hardcoding it there as it can't change. Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through intermediate variables/arguments where it's not needed. Instead initialize in module static variable when MMIO region is mapped and use that within memory_hotplug.c whenever it's required. That way MMIO base specified only at one place and AML with MMIO would always use the same value. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
