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.

ehci_writel() swaps the arguments for address and value. One call
in ehci-mxs ignores that.
This fixes the warning:

Add board-specific callbacks for enabling/disabling port power
into the MXS EHCI controller driver. This is in-line with the
names of callbacks on other systems.

This paramter will later be used to initialize OTG ports in

Rework ehci-mxs so it supports both ports on MX28. It was necessary
to wrap the per-port configuration into struct ehci_mxs_port and pull
out the clock configuration function.

The ehci-mxs driver included the register definitions directly.
Use imx-regs.h instead since it contains proper handling of the
differences between mx23 and mx28.

Kill off ehci-core.h
It was used to specify some static controller data. To support more than
one controller being active at any time we have to carry the controller
data ourselfes. Change the ehci interface accordingly.
NOTE: OMAP implemented the ehci stuff a bit backwards and should be fixed
to do the same thing as other platforms. But the change for now is at least
compile clean.

The CLKCTRL registers are SoC specific so we ought to have it clear on
filename.

As the register accessing mode is the same for all i.MXS SoCs we ought
to use 'mxs' prefix intead of 'mx28'.

This patch renames mx28_register to mx28_register_32 in order to
prepare for the introduction of an 8-bit register, mx28_register_8.
