spi: dw-mmio: add ACPI support
The Hisilicon Hip08 platform, that uses ACPI, has this controller. Let's add ACPI support for DW SPI MMIO-based host. The ACPI ID used is "HISI0173" for the Designware SPI controller of Hisilicon Hip08 platform. Signed-off-by: Jay Fang <f.fangjian@huawei.com> Signed-off-by: Mark Brown <broonie@kernel.org>
