The uart_clps711x_init() returns the platform_driver_register() directly
without checking its return value, if platform_driver_register() failed,
the clps711x_uart is not unregistered.
Fix by unregister clps711x_uart when platform_driver_register() failed.
Fixes: bc00024502ed ("serial: clps711x: Driver refactor")
