[PATCH 1/2] usb: cdns3: Use dma_pool_* api to alloc trb pool

Allocation of DMA coherent memory in atomic context using dma_alloc_coherent() might fail on platforms with smaller DMA region. To fix it, dma_alloc_coherent() is replaced with dma_pool API to allocate a smaller chunk of DMA coherent memory for TRB rings. Fixes: 7733f6c32e36 ("usb: cdns3: Add Cad
