Input: axp20x_pek - add axp20x_pek_probe_input_device helper
Move all input device related initialization into a new
axp20x_pek_probe_input_device helper function.
This introduces one functional change, the input device is now
registered before the sysfs attr get registered. This is not a problem
as the sysfs attr are to configure some long press settings (forced
poweroff) in the hardware and do not interact with the input_device.
This is a preparation patch for not always registering the input dev.
