[PATCH v5 4/7] watchdog: f71808e_wdt: rename variant-independent identifiers appropriately

[Ahmad Fatoum]

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.
