mmc: sdhci: Add Moorestown device support
This adds the basic identifiers. Due to the various chip quirks it's not enough to make MRST support very useful for earlier steppings but that can follow. (I'm currently trying to verify which steps actually matter outside Intel so I can avoid unneeded stuff going upstream) [Extracted from original development] Signed-off-by: JiebingLi <jiebing.li@intel.com> [Folds in fixes] Signed-off-by: Chuanxiao Dong <chuanxiao.dong@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>
