pch_phub: Care FUNCSEL register in PM
commit dd7d7fea29c18b818e94f252a76f495490d399c3 upstream.
Only ML7213/ML7223(Bus-n) has this register.
Currently,this driver doesn't care register "FUNCSEL" in suspend/resume.
This patch saves/restores FUNCSEL register only when the device is ML7213 or
ML7223(Bus-n).
