Input: Fix memory leak in psxpad_spi_probe

In the implementation of psxpad_spi_probe() the allocated memory for
pdev is leaked if psxpad_spi_init_ff() or input_register_polled_device()
fail. The solution is using device managed allocation, like the one used
for pad. Perform the allocation using
devm_input_allocate_polled_device().
