[U-Boot] [PATCH v1 00/16] Add support for DM_USB and DM_USB_DEV to TI's am335x and am43xx_evm platforms

[Jean-Jacques Hiblot]

This series applies on top of the series "Add support for DM_USB and
DM_USB_DEV to TI's K2G platforms" and "Add support for DM_USB and
DM_USB_DEV for TI's DRA7 EVMs and AM57 EVMs platforms."

The am433x platforms can use the generic DWC3 driver instead of relying on
the dwc3-xhci driver.
The am335x platforms use the musb controller. With a bit of work it can be
made to support DM as well. This series only enables DM_USB and DM_USB_GADGET
on am335x_boneblack_vboot. The changes for the other am335x based platforms
will come in a subsequent series that reworks the configs of several TI
boards.

This is part of a work to move all TI's platforms to support DM_USB and
DM_USB_DEV.
As a side effect it makes it easy to support the full USB RDNIS bootflow
(bootrom loads SPL over RNDIS, SPL loads u-boot over RNDIS, u-boot loads
the images over RNDIS)

This series is made of 3 parts:
- some generic changes: rename DM_USB_DEV in DM_USB_GADGET and create
UCLASS_USB_GADGET for the USB peripheral drivers.
- am437x support for DM_USB and DM_USB_GADGET
- am335x support for DM_USB and DM_USB_GADGET


Tested on:
- am4372 evm
- beaglebone black
- am335x evm (to verify that it doesn't break anything)
