ARM: dt: tegra: whistler: add regulators
Whistler uses a Maxim 8907 regulator. Instantiate this. The voltage settings were derived from the schematic. The only exception is the BBAT voltage; the schematic says 1.2v, but the HW can't go that low, so use the HW default of 2.4v instead. Almost all regulators list all driven supply signal names in their regulator-names property. The exception is nvvdd_sv3, which is in turn named 12 more different names on the schematic, so these were omitted for brevity. Signed-off-by: Stephen Warren <swarren@nvidia.com>
