Migrate to use ofnode_* instead of fdt_* so that we may able to use live
dt for usb udc driver.

The xhci.h header file is currently located under drivers/usb/xhci
Move it to the include/usb folder to make it available to drivers that
are not under drivers/usb/xhci

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include <libfdt.h>      -> #include <linux/libfdt.h>
  #include <libfdt_env.h>  -> #include <linux/libfdt_env.h>

Now, include/linux/errno.h is a wrapper of <asm-generic/errno.h>.
Replace all include directives for <asm-generic/errno.h> with
<linux/errno.h>.

<asm-generic/...> is supposed to be included from <asm/...> when
arch-headers fall back into generic implementation. Generally, they
should not be directly included from .c files.

So far, Rockchip SoCs have two kinds of USB2.0 phy, such as Synopsys and
Innosilicon. This patch applys dwc2 usb driver framework to implement
phy_init() and phy_off() methods for Synopsys phy on Rockchip platform.

The index returned by get_sys_clk_index() is not exactly what we expect.
Let's not rely on that and use get_sys_clk_freq() instead.

This fixes missing USB3 devices in the Linux kernel when USB is started
in u-boot. It still doesn't fix missing USB3 devices in u-boot though.
