sdhci-of: fix high-speed cards recognition
eSDHC fails to recognize some SDHS cards, throwing timeout errors:
mmc0: error -110 whilst initialising SD card
That's because we calculate timeout value in a wrong way: on eSDHC hosts
the timeout clock is derivied from the SD clock, which is set dynamically.
As David Vrabel suggested, deriving timeout clock from SD clock is a
common scheme, so let's implement DATA_TIMEOUT_USES_SDCLK quirk and use it
for eSDHC hosts.
Also, from now on we don't need esdhc_get_timeout_clock() callback, so
remove it.
