platform/x86/amd/pmf: Validate the APTS state index
The static slider APTS state index is supplied by the BIOS as an 8-bit
value, but apts_config_store contains only APTS_MAX_STATES entries. An
invalid firmware value can therefore cause amd_pmf_update_slider_v2() to
read beyond the end of the array.
Validate the selected index before applying the slider values and return
an error when it is out of range.
