With the current DLL sequence stability issues are seen in
HS400 and HS200 mode for data transfers.

Rectify the DLL programming sequence as per latest hardware
programming guide and also incorporate support for HS200 and
HS400 DLL settings using the device tree.

Changes from v1:
1. Addressed Tengfei Fan comment, added missing semicolocon
 in sdhci_msm_host structure.

Sachin Gupta (2):
  mmc: sdhci-msm: Add core_major, minor to msm_host structure
