Wolfram Sang 84b84bcf4f watchdog: tangox_wdt: test clock rate to avoid division by 0 
The clk API may return 0 on clk_get_rate, so we should check the result before
using it as a divisor. For this, refactor the code to use a central
error path.

Guenter Roeck 3d29f80813 watchdog: tangox: Print info message using pointer to platform device 
The device pointer in struct watchdog_device should not be used by drivers
and may be removed in the near future. Use the platform device pointer for
info messages instead.
