For easier patch merging and comparison with Linux move the usb
gadget files to where Linux has them. For now do a plain git mv
include/usb include/linux/usb, eventhough there might be some
files which are purely barebox specific.

An mdelay of 1 seems to be necessary on some machines, since
the monsel status does not seem to be accurate. On rare occasions just
working with the phy after this pll check lead to no functional usb.
With this short mdelay this issue was not reported again.

The '_d' suffix was originally meant to distinguish barebox struct
names from Linux struct names. struct driver doesn't exist in Linux,
so we can rename it and remove the meaningless suffix.

The '_d' suffix was originally introduced in case we want to import
Linux struct device as a separate struct into barebox. Over time it
became clear that this won't happen, instead barebox struct device_d
is basically the same as Linux struct device. Rename the struct name
accordingly to make porting Linux code easier.

Linux struct device has the member of_node for the device_node pointer.
Rename this in barebox accordingly to minimize the necessary changes
when porting Linux code. This was done with the semantic patch:
@@ struct device_d E; @@
- E.device_node
+ E.of_node
@@ struct device_d *E; @@
- E->device_node
+ E->of_node
Plus some manual adjustments.

Commit 9474a29003 ("phy: Add deep probe support") added the deep probe
support but this commit was missing the of_phy_get_by_phandle() isn't
calling the internal _of_phy_get() helper. Fix this by moving the
of_device_ensure_probed() call into the of_phy_provider_lookup() helper
which gets called by both functions.

There was no device tree binding in mainline Linux when this driver
was introduced in barebox. This has changed in the mean time, hence
we need to align the clocks and resets in this driver.
This step is a prerequisite for replacing the initial rk3568.dtsi in
arch/arm/dts with the mainline Linux version. For compatibility, the
former is updated accordingly.

This imports following Linux patches by Amelie Delaunay
<amelie.delaunay@foss.st.com>:
phy: stm32: manage 1v1 and 1v8 supplies at pll activation/deactivation
phy: stm32: replace regulator_bulk* by multiple regulator_*
phy: stm32: ensure pll is disabled before phys creation
phy: stm32: ensure phy are no more active when removing the driver
phy: stm32: rework PLL Lock detection
ARM: dts: stm32: add usbphyc vdda1v1 and vdda1v8 supplies on stm32mp151
This makes barebox compatible to the new device tree binding,
reduces our differences to the upstream driver and removes
the power_on, power_off callbacks which are now integrated
into init/exit.
The device tree override is necessary, because unlike with Linux,
barebox regulator core doesn't descend into child nodes to enable
their regulators, but that's a fix for another day.
