SD1.0 cards don't support CMD8 and CMD6
CMD8 result can be used to distinguish the card is SD1.0 or not.
CMD8 result can be used to decide following CMD6 is sent or skip.

Changes in V2:
1.Update description comment for input parameter 'SdVersion1'.
2.Add variables initialize operation to avoid unexpected value.
3.Use TRUE replace with 1 to assign value for BOOLEAN variable.
Changes in V3:
1.Update code format for CL test fail.
2.Fix memory out of bounds when initialize SwitchResp.
