exynos: dts: Support EC tunnel and main TPS65090 regulator
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. Signed-off-by: Simon Glass <sjg@chromium.org>
