staging: fix ste_rmi4 build, depends on INPUT

The synaptics_i2c_rmi4 driver uses input_*() interfaces,
so it should depend on INPUT to fix its build errors:

ERROR: "input_event" [drivers/staging/ste_rmi4/synaptics_i2c_rmi4.ko] undefined!
ERROR: "input_free_device" [drivers/staging/ste_rmi4/synaptics_i2c_rmi4.ko] undefined!
ERROR: "input_register_device" [drivers/staging/ste_rmi4/synaptics_i2c_rmi4.ko] undefined!
ERROR: "input_set_abs_params" [drivers/staging/ste_rmi4/synaptics_i2c_rmi4.ko] undefined!

ERROR: "input_unregister_device" [drivers/staging/ste_rmi4/synaptics_i2c_rmi4.ko] undefined!

          Say Y here if you have a Synaptics RMI4 and
