Subject: [PATCH 4.4 156/193] ARM: tegra: select USB_ULPI from EHCI rather than platform

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

commit a262e87ff354f12447bb6268bd63edf7ba1c20e0 upstream.

For historic reasons, the tegra platform selects USB_ULPI from architecture
code, but that hasn't really made sense for a long time, as the only
user of that code is the Tegra EHCI driver that has its own Kconfig
symbol.

This removes the 'select' statements from mach-tegra and drivers/soc/tegra
and adds them with the device driver that actually needs them.
