So far we've been content with passing physical addresses when
configuring memory addresses into XHCI controllers, but not all
platforms have buses with transparent mappings. Specifically the
Raspberry Pi 4 might introduce an offset to memory accesses incoming
from its PCIe port.
Introduce xhci_virt_to_bus() and xhci_bus_to_virt() to cater with these
limitations, and make sure we don't break non DM users.

To managed it, this patch adds a new DT field

There some vendor quirks for MTK xHCI 0.96 host controller:
1. It defines some extra SW scheduling parameters for HW
to minimize the scheduling effort for synchronous and
interrupt endpoints. The parameters are put into reserved
DWs of slot context and endpoint context.
2. Its TDS in Normal TRB defines a number of packets that
remains to be transferred for a TD after processing all
Max packets in all previous TRBs.

xhci versions 1.0 and later report the untransferred data remaining in a
TD a bit differently than older hosts.
We used to have separate functions for these, and needed to check host
version before calling the right function.
Now Mediatek host has an additional quirk on how it uses the TD Size
field for remaining data. To prevent yet another function for calculating
remainder we instead want to make one quirk friendly unified function.

There might be hardware configurations where 64-bit data accesses
to XHCI registers are not supported properly. This patch removes
the readq/writeq so always two 32-bit accesses are used to read/write
64-bit XHCI registers, similarly as it is done in Linux kernel.
This patch fixes operation of the XHCI controller on RPI4 Broadcom
BCM2711 SoC based board, where the VL805 USB XHCI controller is
connected to the PCIe Root Complex, which is attached to the system
through the SCB bridge.
Even though the architecture is 64-bit the PCIe BAR is 32-bit and likely
the 64-bit wide register accesses initiated by the CPU are not properly
translated to a sequence of 32-bit PCIe accesses.
xhci_readq(), for example, always returns same value in upper and lower
32-bits, e.g. 0xabcd1234abcd1234 instead of 0x00000000abcd1234.

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.

This patch drops all but last 8 bits of register address.
It is possible, because addresses on ULPI bus are 6- or 8-bit.
It is not possible (according to ULPI 1.1 spec) to have more
than 8-bit addressing.
This patch should not cause regressions as all calls to
ulpi_read/write use either structure pointer (@ address 0) or integer
