Tegra's PHY driver has a mix of pr_err() and dev_err(), let's switch to
dev_err() and use common errors message formatting across the driver for
consistency.

UTMI pads are shared by USB controllers and reset of UTMI pads is shared
with the reset of USB1 controller. Currently reset of UTMI pads is done by
the EHCI driver and ChipIdea UDC works because EHCI driver always happen
to be probed first. Move reset controls from ehci-tegra to tegra-phy in
order to resolve the problem.

Tegra's EHCI driver has a build dependency on Tegra's PHY driver and
currently Tegra's PHY driver is built only when Tegra's EHCI driver is
built. Add own Kconfig entry for the Tegra's PHY driver so that drivers
other than ehci-tegra (like ChipIdea UDC) could work with ehci-tegra
driver being disabled in kernels config by allowing user to manually
select the PHY driver.
