sdhci : recompute timeout_clk when needed
when SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK is set, timeout_clk is sdclk. We need to update it when we change sdclk in sdhci_set_clock. This allow to have a more precisse timeout and max_busy_timeout. This can help for command that need a big busy wait (erase, ...). Signed-off-by: Matthieu CASTET <matthieu.castet@parrot.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
