usb: musb: Fix a bug by making suspend interrupt available in device mode 

As a part of aligning the ISR code for MUSB with the specs, the
ISR code was re-written. 

See Commit 1c25fda4a0 (usb: musb: handle 
irqs in the order dictated by programming guide)

With this the suspend interrupt came accidently under CONFIG_USB_MUSB_HDRC_HCD.

The fix brings suspend interrupt handling outside 
CONFIG_USB_MUSB_HDRC_HCD.
