SPDX: Convert all of our single license tags to Linux Kernel style

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.

drivers: USB: OHCI: allow compilation for 64-bit targets

OHCI has a known limitation of allowing only 32-bit DMA buffer
addresses, so we have a lot of u32 variables around, which are assigned
to pointers and vice versa. This obviously creates issues with 64-bit
systems, so the compiler complains here and there.
To allow compilation for 64-bit boards which use only memory below 4GB
anyway (and to avoid more invasive fixes), adjust some casts and types
and assume that the EDs and TDs are all located in the lower 4GB.
This fixes compilation of the OHCI driver for the Pine64.

usb: ohci: Do not reuse ed for interrupt endpoints of different devices

When submitting interrupt packets to an endpoint we only link in the ed
once to avoid some races surrounding unlinking of periodic endpoints,
but we share one ohci_device struct / one set of ed-s for all devices,
which means that if we have an interrupt endpoint at endpoint 1 with one
device, and a non interrupt endpoint 1 with another device we end up
with the same ed linked into both the periodic and async lists, which is
not good (tm).

This commit switches over to using separate ohci_device structs, and thus
separate ed-s for devices with interrupt endpoints, fixing this.

This fixes e.g. matching a usb storage device and keyboard on the same
usb-1 hub not working.

For some reason the ohci code is full with:

AFAICT there is no reason for the mdelay(1) calls. This commit disables them
when building the ohci code for new driver-model using boards. It leaves
the mdelay(1) calls in place when building for older boards, so as to avoid
causing any regressions there.

usb: ohci: Remove unnecessary delays from hc_start and power power-on paths

The usb spec says that we must wait a minimum amount of time after port
power on (exact time is in the hub descriptor), this is something which
we must not only do for root ports but also for external hub ports, which
is why the common usb_hub code already waits a full second after powering
up ports. Having a separate wait for just the root hub in the ohci-hcd
code only leads to doing the waiting twice for the root ports, so drop the
wait from the ohci-hcd code.
