Remove the TEGRA124_CLK_EMC cell value define for tegra124-car

anything and is being replaced with a separate EMC driver with
its own device tree node. Removing the define ensures that any
user will not mistakenly refer to <&tegra_car TEGRA124_CLK_EMC>
instead of <&emc> or similar.

If the clock physically exists in HW, I see no reason to remove it from
the binding definition, even if we don't implement it (or remove the
implementation of it) in the Linux clock driver.
