Subject: [PATCH] iforce: simplify Kconfig depends

The depends on for JOYSTICK_IFORCE is already handled in drivers/input/Kconfig and
drivers/input/joystick/Kconfig.

Remove the depends on JOYSTICK_IFORCE for the *_USB and *_232 connections
by wrapping them in an if/endif block. The second depends on check is still needed
to prevent the iforce driver from being built-in while the connection is a module.

Should the connection depends on be changed to a select similar to the other
joystick drivers?
