usb: gadget: amd5536udc: use free_dma_pools

We have the function free_dma_pools() which frees all the dma pools. Use
it instead of calling all the functions separately. The if conditions
for data_requests and stp_requests are also not required here as this is
the remove function and we are here means probe has succeeded and dma
has been successfully allocated, so they cannot be NULL here.
