spi: zynqmp_gqspi: Fix dma alignment issue
DMA is aligned to ARCH_DMA_MINALIGN(64 bytes), but as per spec, alignment
required is 4bytes only. Change DMA alignment from ARCH_DMA_MINALIGN to
GQSPI_DMA_ALIGN. Remove alignment of data length in non-exponential case.
Some minor improvements in the initialization to initialize gen_fifo
threshold and disable qspi controller while setting config register.
