rpi-config: Add ENABLE_IR variable for infrared

Browse Source 
Users who want infrared device tree overlays gpio-ir and
gpio-ir-tx to be set in config.txt can now easily do it through
variable ENABLE_IR, for example in local.conf:

ENABLE_IR = "1"

By default the GPIO pin for gpio-ir is set to 18 and the pin for
gpio-ir-tx is 17. Both pins can be easily changed by modifying
variables GPIO_IR and GPIO_IR_TX (for example in local.conf).
