mmc:esdhc: disable trim feature on T4240QDS
The timeout value got from eMMC card on T4240QDS is
incorrect. Disable trim and use erase instead.
Remove quirk SDHCI_QUIRK_BROKEN_ADMA to enable ADMA on
T4240QDS.
Calculate the timeout based SD clock when we have qurik
SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK.
