x86/platform/intel-mid: Get rid of duplication of IPC handler

There is no other device handler than ipc_device_handler() and sfi.c already
has a handler for IPC devices.

Replace a pointer to custom handler by a flag. Due to this change adjust
sfi_handle_ipc_dev() to handle it instead of ipc_device_handler().
