Now that machines may select dwc3's working mode (HOST only,
GADGET only or DUAL_ROLE) via Kconfig, let's set dwc3's mode
based on that, rather than fixing it to whatever hardware
says.

This way we can skip initializing Gadget/Host in case
we are using Host-only/Gadget-only mode respectively.

This patch converts the mxs-phy driver from readl_relaxed(), writel_relaxed()
to the plain readl(), writel() functions, which are available on all platforms.

This is done to enable compile time testing on non ARM platforms.

We now have usb_add_phy_dev(), so use it to register with the framework
to be able to find the phy from the USB driver.

Most of otg/otg.c is not otg specific, but phy specific, so move it
to the phy directory.

In DWC3 versions < 2.50a configured without
Hibernation mode enabled, there will be an
extra link status change interrupt if device
detects host-initiated U3 exit.

In that case, core will generate an unnecessary
U3 -> RESUME transition which should be ignored
by the driver.

not all UDC drivers need a proper release function,
for those which don't need it, we udc-core will provide
a no-op release method so we can remove "redefinition"
of such methods in almost every UDC driver.
