[PATCH v1 8/8] watchdog: f71808e_wdt: rename variant-independent identifiers appropriately

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

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_ instead.

This makes code browsing easier, because it's readily apparent whether a
function is variant-specific or not. Also the watchdog_ namespace isn't
used anymore for the driver-internal functions.
