Sanket Parmar	8430e98f2c	usb: cdns3: Optimize DMA request buffer allocation ... dma_alloc_coherent() might fail on the platform with a small DMA region. To avoid such failure in cdns3_prepare_aligned_request_buf(), dma_alloc_coherent() is replaced with dma_alloc_noncoherent() to allocate aligned request buffer of dynamic length.

Sanket Parmar	b9b1eae761	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.
