Some laptops, such as Lenovo 3000 N100, require keyboard controller reset in order to have touchpad operable after suspend to RAM. Even if box does not need the reset it should be safe to do so, so instead of chasing after misbehaving boxes and grow DMI tables, let's reset the controller unconditionally.

We need to call platform_device_unregister(i8042_platform_device) before calling platform_driver_unregister() because i8042_remove() resets i8042_platform_device to NULL. This leaves the platform device instance behind and prevents driver reload.

Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix.
