Commit af566a0be6e49 ("usb: dwc3: omap: get rid of dma_status") rendered
reading DMA status from the H/W even more redundant. The variable hasn't
been read/used since 2016. Remove the set but unused variable and the call
which populates it.
Fixes the following W=1 warning:
drivers/usb/dwc3/dwc3-omap.c: In function ‘dwc3_omap_probe’:
drivers/usb/dwc3/dwc3-omap.c:460:8: warning: variable ‘reg’ set but not used [-Wunused-but-set-variable]
460 | u32 reg;
| ^~~
