[U-Boot] [PATCH 05/10] exynos5: support tps65090 pmic

[Simon Glass <sjg@chromium.org>]

From: Aaron Durbin <adurbin@chromium.org>

The TSP65090 is a PMIC on some exynos5 boards. The init function is
called for the TPS65090 pmic. If that device is not a part of the device
tree (returns -ENODEV) then continue. Otherwise return a failure.
