[PATCH 2/2] arm: boot: dts: am4372: enable dwc3 suspend PHY quirk

[Tony Lindgren]

* Felipe Balbi <balbi at ti.com> [141106 09:40]:
> Whenever Suspend PHY bit is set on AM437x devices,
> USB will not work due to Set EP Configuration command
> always failing.
> 
> This was only found after a recent commit 2164a47 (usb:
> dwc3: set SUSPHY bit for all cores, which will be merged
> for v3.19) added a missing *required* step to dwc3
> initialization. Synopsys Databook requires that we enable
> Suspend PHY bit after initialization but that, unfortunately,
> breaks AM437x.

This should be safe to queue along with the related USB
changes:
