Subject: [PATCH v2 2/7] 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 v1:
1. Fixed voltage regulators were used for vbus-supply
2. Added UTMI PHY timing Parameters to DT.
