exynos: dts: Support EC tunnel and main TPS65090 regulator

Browse Source 
On pit and pi the TPS65090 regulator is connected only to the EC and we
must use a tunnel to get to it. The existing U-Boot support relies on a
special driver. Add a tunnel definition so that the new device-model
TPS65090 driver can be used unmodified.
