mmc: sdhci-of-at91: rework clocks management to support SAM9x60 device
In the SAM9x60 SoC, there are only two clocks instead of three for the
SDHCI device. The base clk is no longer provided, it is generated
internally from the mult clk.
The values of the base clk and mul in the capabilities registers may not
reflect the reality as the mult clk is a programmable clock which can take
several rates. As we can't trust those values, take them from the clock
tree and update the capabilities according to.
As we can have the same pitfall, in some cases, with the SAMA5D2 Soc,
stop relying on capabilities too.
