mmc: sdhci: move timeout_clk dynamically calculation code into common code
The timeout_clk calculation code for SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK case
is common and could be moved into common sdhci_do_set_ios, then platform code
which is not using sdhci_set_clock does not need to write the same code again.
