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 1c25fda4a09e8229800979986ef399401053b46e (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.
