The two regulator drivers in the drivers/soc/ directory fail to build
when regulator support is disabled:
aarch64-linux-ld: drivers/soc/tegra/regulators-tegra20.o: in function `tegra20_regulator_reboot':
regulators-tegra20.c:(.text.tegra20_regulator_reboot+0x4c): undefined reference to `regulator_sync_voltage_rdev'
aarch64-linux-ld: regulators-tegra20.c:(.text.tegra20_regulator_reboot+0x58): undefined reference to `regulator_sync_voltage_rdev'
aarch64-linux-ld: drivers/soc/tegra/regulators-tegra30.o: in function `tegra30_regulator_reboot':
regulators-tegra30.c:(.text.tegra30_regulator_reboot+0x44): undefined reference to `regulator_sync_voltage_rdev'
aarch64-linux-ld: regulators-tegra30.c:(.text.tegra30_regulator_reboot+0x50): undefined reference to `regulator_sync_voltage_rdev'
Add a Kconfig dependency to avoid this configuration.

Hello Arnd,
Thank you for the patch!
I also sent out the fix [1] about a month ago and was trying to ping
Thierry. Unfortunately there was no reaction so far and now Thierry is
on vacation.

It looks like my variant of the fix should be a bit more correct since
it won't build the regulator drivers if both TEGRA=n and REGULATOR=n.
I guess it should be fine if you could take the patch directly, perhaps
Jon could ack the patch for that. Otherwise we could wait for Thierry to
return.
