ENGR00213944-02: mmc: sdhci: [MX6] support SD v3.0 memory cards.
- Add variable pad speed setting per SD clk freq.
- Add SD3.0 support on SD1, SD2, and SD3.
- Enhance drive strength on SD pad to improve its compatibility.
- change the definition of pad speed changing interface
- combine pad speed setting for different SD host controllers into one function.
