watchdog: f71808e_wdt: rename variant-independent identifiers appropriately
Code for the common parts of the driver either uses watchdog_ as prefix for the watchdog API or f71808e_ for everything else. The driver now supports 9 more variants besides the f71808e, so let's rename the common parts to start with fintek_wdt_ instead. This makes code browsing easier, because it's readily apparent that functions are not variant-specific. Some watchdog_-prefixed functions remain, but these will be dropped altogether with the move to the kernel watchdog API in a later commit.
