Quanyang Wang 5980a3b9c9 spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails 
[ Upstream commit 126bdb606fd2802454e6048caef1be3e25dd121e ]

The spi controller supports 44-bit address space on AXI in DMA mode,
so set dma_addr_t width to 44-bit to avoid using a swiotlb mapping.
In addition, if dma_map_single fails, it should return immediately
instead of continuing doing the DMA operation which bases on invalid
address.

This fixes the following crash which occurs in reading a big block
from flash:

[  123.633577] zynqmp-qspi ff0f0000.spi: swiotlb buffer is full (sz: 4194304 bytes), total 32768 (slots), used 0 (slots)
