usb: i.MX: Add i.MX28 support
...
The existing i.MX chipidea support can be used for i.MX28 as well. The
main difference is that the i.MX28 doesn't have a usbmisc unit, so the
bulk of this patch makes this unit optional in the driver.

usb: imx: implement support for limiting host to full speed
...
This is needed when host is known to not work properly in high speed
mode.
In linux, chipidea driver supports 'maximum-speed' device tree property.
When that is set to "full-speed", driver sets PFSC bit in PORTSC
register, which disallows use of high speed mode.
This patch implements same support for barebox.
Important technical detail is that PFSC bit is cleared by port reset,
thus setting it has to be done in ehci->init() callback which is called
after ehci_reset().

...
i.MX7 has two usbmisc devices, so we cannot use global instance
variables anymore. Create a driver private data struct for it.

chipidea-imx: allow phymode configuration in pdata
...
it's currently only handled through DT and for i.MX25 OTG port (at least),
we need to configure portsc to get host mode working but it actually fails
as ci->phymode is 0 which is USBPHY_INTERFACE_MODE_UNKNOWN

USB i.MX: Add chipidea driver support
...
For proper USB function the usbmisc registers have to be initialized.
This patch adds a driver which matches for the usbmisc registers. This
driver is called from a new driver which binds to the USB ports to
configure the misc registers. After that the driver registers the EHCI
driver and an ULPI transceiver if necessary. Currently only host mode
is supported, but device support can be added later.
