Usually the digital and anolog phys use the same reference clock,
but on some platforms, they are separated, so add another optional
clock to support it.
In order to keep the clock names consistent with PHY IP's, use
the da_ref for anolog phy and ref clock for digital phy.

Sometimes the reference clock of USB3 PHY comes from oscillator
directly, and no need refer to a fixed-clock in DTS anymore
if make it optional.

Add a property usb-role-switch to tell the driver that use
USB Role Switch framework to handle the role switch,
it's useful when the driver has already supported other ways,
such as extcon framework etc.

Add fwnode_usb_role_switch_get() to make easier to get
usb_role_switch by fwnode which register it.
It's useful when there is not device_connection registered
between two drivers and only knows the fwnode which register
usb_role_switch.

Due to extcon is not allowed for new bindings, and the
Dual-Role switch is supported by USB Role Switch,
especially for Type-C drivers, so register a USB Role
Switch to support the new way

Due to the requirement of usb-connector.txt binding, the old way
using extcon to support USB Dual-Role switch is now deprecated
when use Type-B connector.
