mmc: sdhci-msm: Add chip version check for errata

There was a hardware fix in DLL of SDCC.
The fix is on 1.1 version of the SoC.

This is a method to distinguish between the two
different versions of the SoC by reading the minor
revision number as:
00 : rev 1.0
01 : rev 1.1

Using this method this errata can be worked
around for the specific chip version.
