Currently runtime PM is only enabled if a valid host wake IRQ was found. However it is used in ways which seem unrelated to host wake: E.g., runtime PM is used to force the Bluetooth device on for 5 sec after a complete packet has been received. Afford this functionality to devices which lack an IRQ by moving the code to enable runtime PM from bcm_request_irq() to bcm_setup().
