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.

Fixes: 783807436f36 ("soc/tegra: regulators: Add regulators coupler for Tegra30")
