spi: spi_amd: Replace ioread/iowrite calls

All `ioread*` and `iowrite*` functions are better suited for architecture
independent code to ensure portability across different architectures.
Since AMD SoCs support only the x86 architecture, replacing all `ioread*`
and `iowrite*` calls with `read*` and `write*` calls can reduce the
overhead of ensuring portability and increase the speed of I/O operations.
