After calling clk_prepare_enable(), clk_disable_unprepare() needs
be called when prepare_timing_change() failed.

Add modularization support to the Tegra124 EMC driver, which now can be
compiled as a loadable kernel module.
Note that EMC clock must be registered at clk-init time, otherwise PLLM
will be disabled as unused clock at boot time if EMC driver is compiled
as a module. Hence add a prepare/complete callbacks. similarly to what is
done for the Tegra20/30 EMC drivers.

This code is only used on Tegra124, so rename it accordingly to make it
more consistent with other file names.
While at it, also get rid of the TEGRA_CLK_EMC Kconfig symbol that's
really just an alias for TEGRA124_EMC.
