synopsys/dwc2: fix SOF interrupt handling

gschorcht · gschorcht · commit 4c510c12b1d0 · 2023-02-27T09:54:45.000+01:00
SOF is not a flag of the GOTGINT register but of the GINTSTS register. Therefore the flag must be written in the GINTSTS register instead of the GOTGINT register to clear the interrupt.
