struct platform_device::id was only set by board code, but since i.MX
became a devicetree-only platform, this will always be -1
(PLATFORM_DEVID_NONE).

Note: of_alias_get_id() returns a negative number on error and base
treats all negative errors the same, so we need not add any additional
error handling.

This looks like I can pick it up separately from the rest? Is that right?
