spi: spi-synquacer: Fixed build on architectures missing readsl/writesl series

kbuild test reported that alpha and some of the architectures
are missing readsl/writesl series.
Use more portable ioread32_rep()/iowrite32_rep() series.

Fixes: b0823ee3 ("spi: Add spi driver for Socionext SynQuacer platform")
