watchdog: sp5100_tco: Clean up function and variable names
Use more common function and variable names. Use pdev instead of dev for platform device. Use sp5100_tco_probe() instead of sp5100_tco_init() for the probe function. Drop sp5100_tco_cleanup(); just move the code into sp5100_tco_remove(). Use sp5100_tco_init() instead of sp5100_tco_init_module() for the module initialization function. Use sp5100_tco_exit() instead of sp5100_tco_cleanup_module() for the module exit function. Use consistent defines for accessing the watchdog control register.
