[U-Boot] [PATCH 14.5/15] tegra: Keep virt support disabled by default

Upstream Linux is broken with default configs when PSCI is enabled.
So the user should explicitly enable virtualization, e.g. when she
disabled CONFIG_CPU_IDLE in Linux (in which case it's safe to use). We
can revert this workaround once Linux got fixed.
