spi: zynqmp: Fix for qspi dma when accessing address space beyond 32-bit

dma_set_mask should be called before registering to spi_master.
In the current flow dma_set_mask is set to 44 bit but after
registering to spi_master. because of this, qspi dma is not able
to access beyond 32-bit address space. during spi_register_master,
core will do some dma transfers, hence not able to access beyond
32-bit address space.
