[PATCH -next] staging: fix ste_rmi4 build, depends on INPUT

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

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