security/intel/stm: Reset BIOS resource list on every stm_setup call
Some platforms run the smm_relocation function twice during initialization.
This results in the BIOS resource list becoming twice as long. Also,
testing has shown that elements of the list created in the first interation
may have invalid data included in the resource list.
This patch resolves these issues by reseting the list every time stm_setup
is involked.
This patch has been tested on the Purism L1UM-1X8C
