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.

sysfs files. Let anyone read those.

now that no UDC driver touches gadget.dev.release
we can assign our release function to it without
being afraid of breaking anything.

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.
