Subject: [PATCH 4/5] usb: dwc2: gadget: fix default value for gadget-dma-desc

The current default for gadget DMA descriptor results on bcm2835 in a
unnecessary error message:

  Invalid value 1 for param gadget-dma-desc

So fix this by using hw->dma_desc_enable as default value.

Fixes: dec4b55677e ("usb: dwc2: gadget: Add descriptor DMA parameter")
