[PATCH 1/2][Artful][SRU Zesty] ACPI / APD: Add clock frequency for Hisilicon Hip07/08 I2C controller

[dann frazier]

From: Hanjun Guo <hanjun.guo at linaro.org>

BugLink: https://bugs.launchpad.net/bugs/1708293

I2C clock frequency of Designware ip for Hisilicon Hip07 is 200M,
but 250M for Hip08, use two ACPI IDs to differentiate them.
