Subject: [PATCH 3/3] corenet: Switch to of_platform_default_populate

From: Andy Fleming <[email-masked]>
Date: Sun, 23 Oct 2016 18:48:39 -0500

Many of the embedded powerpc boards use an array of device names
to register the devices from the device tree. Instead, we can use
of_platform_default_populate(), which will iterate through all the root nodes and register them.

This is necessary to enable the gpio power/reset pins on the Cyrus board.

I have confirmed that the PCI devices are registered and that the power/reset
drivers are registered (and functional). I also tested USB, and saw the
onboard MMC card report in, so some of the SoC devices are definitely there.

If this doesn't break the other corenet boards, I'd be happy to make the
same change for the other powerpc boards.
