Add a quirk to clear the GUSB2PHYCFG.ENBLSLPM bit, which controls
whether the PHY receives the suspend signal from the controller.
Refer to commit ec791d149bca("usb: dwc3: Add dis_enblslpm_quirk")
in Linux Kernel.

Add a quirk to clear the GUSB2PHYCFG.U2_FREECLK_EXISTS bit,
which specifies whether the USB2.0 PHY provides a free-running
PHY clock, which is active when the clock control input is active.
Refer to commit 27f83eeb6b42("usb: dwc3: add dis_u2_freeclk_exists_quirk")
in Linux Rockchip Kernel.

Let move 8/16-bit UTMI+ interface initialization into DWC3 core init
that is convenient for both DM_USB and u-boot traditional process.

RK3399 Type-C PHY is required that must hold whole USB3.0 OTG controller
in resetting to hold pipe power state in P2 before initializing the PHY.
This commit fixed it and added device compatible for rockchip platform.

Reset delay should be handled by the reset controller, no ?

This is dwc3's reset phandle linked to CRU on Rockchip platform,
however, the reset driver just update the register value, and the timing
need to be guaranteed by invoker itself.

If the reset controller needs a delay after toggling the bit, then it
should add such delay, no ?

But normally the time a reset line should be pulled low/high whatever
is specified in the datasheet of the relevant controller (type-c phy here).
My most recent experience is with dsi panels, where the panel-controller's
datasheet specifies how long its reset line needs to be pulled to achieve
a full reset of the controller - and I guess it will be similar with other
controllers.
So to me this doesn't look like a property of the reset controller, but the
controller connected to the reset line - especially as different
"reset-clients" will have different timing constraints.

That's up to Frank to find out then.
