usb: chipidea: Only read/write OTGSC from one place
commit f60f8ccd54e03c1afafb2b20ceb029a0eaf7a134 upstream.
With the id and vbus detection done via extcon we need to make
sure we poll the status of OTGSC properly by considering what the
extcon is saying, and not just what the register is saying. Let's
move this hw_wait_reg() function to the only place it's used and
simplify it for polling the OTGSC register. Then we can make
certain we only use the hw_read_otgsc() API to read OTGSC, which
will make sure we properly handle extcon events.
