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.

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.

As the register accessing mode is the same for all i.MXS SoCs we ought
