usb: common: create Kconfig file

Browse Source 
Create Kconfig file for USB common core, and move USB_LED_TRIG
and USB_ULPI_BUS configs into the new file from the parent Kconfig,
it will help to add new configs later.

This option adds LED triggers for USB host and/or gadget activity.
Say Y here if you are working on a system with led-class supported

UTMI+ Low Pin Interface (ULPI) is specification for a commonly used
USB 2.0 PHY interface. The ULPI specification defines a standard set
of registers that can be used to detect the vendor and product which
allows ULPI to be handled as a bus. This module is the driver for that
bus.
The ULPI interfaces (the buses) are registered by the drivers for USB
controllers which support ULPI register access and have ULPI PHY
attached to them. The ULPI PHY drivers themselves are normal PHY
drivers.
ULPI PHYs provide often functions such as ADP sensing/probing (OTG
protocol) and USB charger detection.
To compile this driver as a module, choose M here: the module will
be called ulpi.
