[PATCH V3 2/2] mmc:sdhci-pci-o2micro:Make the SD clock's base clock frequency correctly according to different card mode

[fred <fred.ai@bayhubtech.com>]

From: Fred Ai <fred.ai@bayhubtech.com>

Remove SDR104 card, SD clock's base clock
frequency is not right when insert SD2.0/SDR50 card

Signed-off-by: Fred Ai <fred.ai@bayhubtech.com>

Change in V3:
1.Set SD clock's base clock frequency to 208MHz when card mode is SDR104/HS200.
2.Set SD clock's base clock frequency to 200MHz when card mode is SD2.0/SDR50.
