usb: host: tegra: Remove leftover code
ehci-tegra calls devm_usb_get_phy, which will never succeed since the Tegra
PHY does not register itself with the PHY subsystem. It is also completely
redundant since the code has already located a PHY via an internal API.
Call otg_set_host unconditionally to simplify the code since it should
be safe to do so.
