Some host controllers will not operate without a hardware timeout that is limited in value. However large discards require large timeouts, so there needs to be a way to specify the maximum discard size.
A host controller driver may now specify the maximum discard timeout possible so that max_discard_sectors can be calculated.
However, for eMMC when the High Capacity Erase Group Size is not in use, the timeout calculation depends on clock rate which may change. For that case Preferred Erase Size is used instead.
