Subject: [PATCH v4 3/8] ARM: tegra: update device trees for USB binding rework
This patch updates all Tegra board files so that they contain all the
properties required by the updated USB DT binding. Note that this patch
only adds the new properties and does not yet remove the old properties,
in order to maintain bisectability. The old properties will be removed
once the driver has been updated to assume the new bindings.
Signed-off-by: Venu Byravarasu <vbyravarasu@...dia.com>

delta from v3:
Added status field to USB PHY DT nodes.
delta from v2:
1. Removed dr_mode setting to otg, due to lack of knowledge of all Vbus supplies,
on all target platforms.
2. All changes related to 'nvidia,phy-reset-gpio' were moved to patch 2 of the
same series.
delta from v1:
1. Fixed voltage regulators were used for vbus-supply
2. Added UTMI PHY timing Parameters to DT.
