arm64: dts: exynos: Fix silent hang after boot on Espresso
[ Upstream commit b072714bfc0e42c984b8fd6e069f3ca17de8137a ]
Once regulators are disabled after kernel boot, on Espresso board silent
hang observed because of LDO7 being disabled. LDO7 actually provide
power to CPU cores and non-cpu blocks circuitries. Keep this regulator
always-on to fix this hang.
