serial: 8250_omap: fix wake irq cleared during suspend

Browse source

The wake irq was cleared in shutdown(), which runs during the suspend
sequence, making it impossible to wake the system via UART.
Move wake irq setup to probe() and teardown to remove() so the irq
remains armed during suspend when the UART is a wakeup source.
