This commit converts i.MX5'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-mx6.c code.

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.

Most of ehci-fsl header describe USB controller
designed by Chipidea and used by various SoC vendors.
This patch renames it to a generic header: ehci-ci.h
Contents of file are not changed (so it contains several
references to freescale SoCs).

These are a pain with driver model because we might have different EHCI
drivers which want to implement them differently. Now that they use
consistent function signatures, we can in good conscience move them to
a struct.

Currently we have the following behavior in ehci_hcd_init()
- Read csmr1 register, clear bit 26 and then set bit 26.
However a little bit later we call set_usb_phy_clk() which clears bit 26, so
let's get rid of the unnecessary code.

A custom board_ehci_hcd_init() may be unneeded, so add a weak default
implementation doing nothing.
By the way, use simple __weak from linux/compiler.h for
board_ehci_hcd_postinit() instead of weak alias with full attribute.

The i.MX51 has a single USB PHY clock, while the i.MX53 has two. These 3 clocks
have different clock gate control bit-fields.
The existing code was correct only for i.MX53, so this patch fixes the i.MX51
use case.

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.

It's derived from ehci-mxc and uses the header files of the
ehci-fsl interface. The callback board_ehci_hcd_init() has
been introduced to allow for board-specific setup when USB
is started.
