07791e8d05 usb: ehci: dm: Convert i.MX28 ehci code to driver model
This commit converts i.MX28's EHCI USB host driver to driver model
(DM_USB). It is a straightforward conversion (to reuse as much code
as possible), based on ehci-mx5.c code.

2d431e33dc usb: ehci: Move common mxs code to separate functions (ehci_hcd_{stop|start})
Those functions will be re-used when the ehci MXS driver (for imx28)
will be converted to also support CONFIG_DM_USB.

No functional changes introduced - only cosmetic changes (u32 type)
and alignment to pass checkpatch.

83d290c56f 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.

6f7c92db4c usb: ehci: mxs: fix swapped argument in ehci_writel()
ehci_writel() swaps the arguments for address and value. One call
in ehci-mxs ignores that.

This fixes the warning:

dd24b57bb7 usb: ehci: mxs: Add board-specific callbacks
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.

afa8721099 mxs: Make ehci-mxs multiport capable
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.

47f1331506 mxs: Squash the header file usage in ehci-mxs
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.

676ae068d9 usb: ehci: rework to take advantage of new lowlevel interface
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.
