ehci-mx6: Update EHCI driver to support OTG0 on i.MX7ULP
The ULP has two USB controllers. These two controllers have similar NC
registers layout as i.MX7D. But OTG0 uses UTMI PHY simliar as i.MX6, not
the integrated PHY on i.MX7D. The OTG1 needs off-chip HSIC PHY or ULPI PHY
to work.
This patch only supports OTG0 with UTMI PHY.

usb: ehci-mx6: Fix bus enumeration for iMX7 SoCs
This fixes the issues with calculation of controller indexes in
ehci_usb_bind() for iMX7, as USB controllers on iMX7 SoCs aren't
placed next to each other, and their addresses incremented by 0x10000.
Which was leading to usb enumeration issues:

ARM: DTS: keystone: complete the description of the USB PHY devices
As the PHY driver now handles the transitions of USB power domain, we
must add this information in the node of each PHY.
Also, the phy are expected in the "phys" property, not "usb-phys".
Also add the aliases for the USB ports on boards with more than a single
port.
configs: k2g_evm_defconfig: disable XHCI_DWC3 and enable KEYSTONE_USB_PHY
KEYSTONE_USB_PHY is now required for proper USB operations.
XHCI_DWC3 can be disabled as the xhci-dwc3 is not used anymore
USB_DWC3_GADGET can also be removed, it is now selected automatically.
phy: keystone-usb: handle the transition of the USB power domain
There is no proper power domain support for the keystone platforms.
However we need to turn off the USB domains before jumping to linux or it
fail to boot (observed with k2e and k2l platforms).
This can be done in the PHY driver as it is dedicated only to the keystone
platforms and matches the required on/off sequence.
usb: dwc3: Kconfig: get rid of obsolete mode selection
The mode selection for the DWC3 is kind of obsolete. The driver does not
have to be host only or gadget only. This choice is confusing.
All the remaining callers of dwc3_uboot_init() explicitly set dr_mode
before calling the function, so none rely on a default behavior.
Remove the choice menu and keep only the USB_DWC3_GADGET option. Enable it
by default if USB_GADGET and USB_DWC3 are enabled.
It must be disabled for the evb-rk3328 as it uses DWC2 for the gadget and
DWC3 for the host.
usb: dwc3: Add dwc3_of_parse() to get quirks information from DT
Add a new function that read quirk and configuration information from the
DT. The goal is to allow platforms using their own version of DWC3 driver
to migrate to the generic DWC3 driver.
The function is adapted from the function dwc3_get_properties() in the
linux dwc3 driver introduced in commit c5ac6116db35d.
usb: dwc3-generic: add a new host driver that uses the dwc3 core
Currently the host driver used by dwc3-generic is "xhci-dwc3". This is
a functional driver but it doesn't use the dwc3 core and, in particular,
it lacks some bits that may be important.
For example on the k2 platforms, it is important that the phy are properly
suspended when the USB is not used anymore. The dwc3 core also has a
partial support for quirks.
The new driver can be used as a drop-in replacement for "xhci-dwc3".
In terms of implementation, it may seem strange that 2 private structures
dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this
is simply that the xhci layer expects a struct xhci_ctrl at the beginning
of the private data and it seemed wasteful to include it also for the
peripheral case.
