cpu/amd/model_fxx/powernow_acpi.c: Remove set but unused variable `Start_vid`

Removing `-Wno-unused-but-set-variable` from `CFLAGS` the build for the
    ASRock 939A785GMH fails with the following error.

CC         cpu/amd/model_fxx/powernow_acpi.ramstage.o
    	src/cpu/amd/model_fxx/powernow_acpi.c: In function 'pstates_algorithm':
    	src/cpu/amd/model_fxx/powernow_acpi.c:761:25: error: variable 'Start_vid' set but not used [-Werror=unused-but-set-variable]
    	cc1: all warnings being treated as errors

When adding support for PSS object generation for AMD pre Family Fh CPUs
    (199c694f) the function `pstates_algorithm` was copied and adapted, but
    `Start_vid` is not needed anymore as a static table is used. So remove
    the variable `Start_vid`.
