Subject: [PATCH -next v2] spi: rockchip-sfc: Use devm_platform_ioremap_resource()

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_ioremap_resource(), as this is exactly what this
function does.

--According to Tudor's suggestion, use devm_platform_ioremap_resource() and
