cpu/x86/smm_stub.S: Drop smm_runtime from the stub

Browse Source 
The parameters that the permanent handler requires are pushed directly
to the permanent handlers relocatable module params.

The paremeters that the relocation handler requires are not passed on
via arguments but are copied inside the ramstage. This is ok as the
relocation handler calls into ramstage.
