* spi: spi-mem: zynq-qspi: Fix build error on architectures missing readsl/writeslNaga Sureshkumar Relli2019-05-021-4/+4
| | | | | | | | | | Alpha and some of the architectures are missing readsl/writesl functions. so the zynq-qspi driver won't be able to build on these arches. hence use ioread32_rep()/iowrite32_rep() instead of readsl()/writesl().
