usb: f_gsi: Disable function remote wake-up capability for DPL

If driver allows function remote wake-up for DPL interface.
windows10/8 host may suspend the DPL function in SS mode.
When we receive Function Suspend for usb interface. gsi_suspend()
blocks ringing of doorbell by USB controller to IPA GSI and schedule
usb_ipa_w work with event EVNT_SUSPE. This will block the GSI to IPA
path for other GSI interfaces in the compositions.

Hence disable function remote wake-up capability for DPL interface.
