ltq-adsl-mei: use the same file name for all variant

Due to limitations in the symvers treatment and the mei drivers
exporting the same funtions, modpost might use the wrong mei driver
to link against.

Work around this by renaming them all to the same name, making it
always the "right" module name even if the wrong file was used.
