[PATCH v4 2/3] watchdog: w83627hf_wdt: Report the probed chip name via WDIOC_GETSUPPORT

[Paul Louvel]

The watchdog identity string reported via WDIOC_GETSUPPORT has always
been hardcoded to "W83627HF Watchdog", even though this driver supports
a wide range of Nuvoton/Winbond Super I/O chips.

This is misleading, since the driver itself correctly log the chip name
in wdt_init(), but could report later a different chip name with
WDIOC_GETSUPPORT.

Instead format the identity at probe time using the actual chip name
that was detected.
