Krishna Kurapati 0f47e4fd6f usb: dwc3: core: Skip setting event buffers for host only controllers
[ Upstream commit 89d7f96299 ]

On some SoC's like SA8295P where the tertiary controller is host-only
capable, GEVTADDRHI/LO, GEVTSIZ, GEVTCOUNT registers are not accessible.
Trying to access them leads to a crash.

For DRD/Peripheral supported controllers, event buffer setup is done
again in gadget_pullup. Skip setup or cleanup of event buffers if
controller is host-only capable.
