The fixed issues include:
1. break cmd exec earlier if the card isn't identified successfully
2. Use BaseClk if the target clock is larger than BaseClk
3. Use PIO rather DMA mode for sample clock tuning to strictly
follow SD HC spec.
4. Enhance error handling of tuning procedure
5. Check supported bus mode before switch
