REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1140

Some of the boards report that just after we change the clock frequency to 200MHz link is unable to stabilize fast enough and when driver sends the CMD13 it will often fail randomly with CRC error. To protect against this kind of random failures this patch series will make the driver retry the commands that failed due to random CRC errors.

Since async code has not yet been tested it has been put into separate patch. That patch is not needed to solve most pressing CMD13 issues.

changes in v2:
-Split first patch into bugfix and refactor
-Normal interrupt status register will now only be read once during SdMmcCheckTrbResult
-We will no longer clear the data transfer timeout error in SdMmcCheckAndRecoverErrors. Instead we will immedieatly return for such case and register reset will be done in next SdMmcExecTrb

Tets performed:
-Boot eMMC in HS400
-Boot eMMC in HS400 with simulated CRC error on every first CMD13

For the series,
Reviewed-by: Hao A Wu <hao.a.wu@intel.com>

I will wait a couple of days to see if there are comments from other reviewers
before pushing the series.

Best Regards,
Hao Wu
