mb/system76/cml-u: Fix inclusion of romstage.c
When lemp9 was converted to a variant in CB:64528, the Makefile was not
updated to handle the variant-specific `romstage.c`. This, as would be
expected, caused memory init errors and broke boot on CML-U boards.
Tested lemp9 boots to payload again.
Fixes: 5b7b04c938f2 ("mb/system76/cml-u: Convert lemp9 to a variant")
