ACPI / APD: Add clock frequency for Hisilicon Hip07/08 I2C controller
I2C clock frequency of Designware ip for Hisilicon Hip07 is 200M, but 250M for Hip08, use two ACPI IDs to differentiate them. Signed-off-by: Hanjun Guo <hanjun.guo@linaro.org> Reviewed-by: Kefeng Wang <wangkefeng.wang@huawei.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
