Input: add generic input driver to read encoded GPIO lines Add a driver to read group of GPIO lines and provide its status as a numerical value as input event to the system. This will help in interfacing devices, that can be connected over GPIOs, that provide input to the system by driving GPIO lines connected to them like a rotary dial or a switch. For example, a rotary switch can be connected to four GPIO lines. The status of the GPIO lines reflect the actual position of the rotary switch dial. For example, if dial points to 9, then the four GPIO lines connected to the switch will read HLLH(0b'1001 = 9). This value can be reported as an ABS_* event to the input subsystem.

Input: gpio_decoder - switch to using polled mode of input devices We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts gpio_decoder driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV.
