Bluetooth: btusb: request wake pin with NOAUTOEN

Badly-designed systems might have (for example) active-high wake pins
that default to high (e.g., because of external pull ups) until they
have an active firmware which starts driving it low.  This can cause an
interrupt storm in the time between request_irq() and disable_irq().

We don't support shared interrupts here, so let's just pre-configure the
interrupt to avoid auto-enabling it.

Fixes: fd913ef7ce61 ("Bluetooth: btusb: Add out-of-band wakeup support")
Fixes: 5364a0b4f4be ("arm64: dts: rockchip: move QCA6174A wakeup pin into its USB node")
