[PATCH 2/4] of/platform: return error on of_platform_device_create_pdata failure

[Rob Herring <robherring2@gmail.com>]

From: Rob Herring <robh@kernel.org>

of_platform_populate does not return an error if creating the platform
device fails. This means almost any error from driver core cannot be
detected by the caller. Fix this.
