[PATCH v2] spi: spi-synquacer: Fixed build on architectures missing readsl/writesl series

[Masahisa Kojima <masahisa.kojima@xxxxxxxxxx>]

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

Fixes: b0823ee35cf9b ("spi: Add spi driver for Socionext SynQuacer platform")
Reported-by: kbuild test robot <lkp@xxxxxxxxx>
Signed-off-by: Masahisa Kojima <masahisa.kojima@xxxxxxxxxx>

Changes since v1:
        # Instead of updating Kconfig, use more portable
          ioread32_rep()/iowrite32_rep() series.
