For the past few days -next has been failing to build an arm64
allmodconfig due to:

| drivers/built-in.o: In function `tegra124_132_clock_init_post':
| :(.init.text+0x285d8): undefined reference to `tegra_emc_init'

This is triggered by d035fdfa27ac124bc8 (arm64: Add Tegra132 support)
which enables ARCH_TEGRA and ARCH_TEGRA_132_SOC for arm64 which in turn
causes clk-tegra124 to be built on arm64.  That driver relies on
TEGRA124_EMC but that depends on ARCH_TEGRA_124_SOC which is 32 bit
only.

We either need the EMC driver for Tegra132, a stub or some ifdefs.

It also looks like there's an issue if the memory controller driver is
not enabled (which looks to be something that can be controlled by the
user) but I've not checked properly.

It's actually triggered by a newer patch (f8fd257fabf0 "clk: tegra: Add
EMC clock driver") which adds this new dependency.

Tegra132 uses the same memory controller as Tegra124, so clk-emc should
work on both. I likely overlooked this when applying the patches. I also
have a local patch for this that I haven't pushed yet. Will do it right
away.

I'll do some testing to see if I can break it by permutating some of the
Kconfig symbol combinations.

The ARM64 allmodconfig finally finished building and I've pushed
something that should hopefully fix things.
