This patch series originates from a bigger patch series:
https://lists.denx.de/pipermail/u-boot/2022-December/502865.html
Register ohci-at91 driver into Driver Model. In order for the VBUS to
stay enabled, a `child_pre_probe` method has been added to overcome the
DM core disabling it in `usb_scan_device`: when the generic `device_probe`
method is called, the pinctrl is processed once again, undoing whatever
changes have been made in our driver's probe method.
In order to enable USB on SAMA7G5 the addition of the USB 2.0 PHY
drivers were required.
v1 -> v2:
- squashed previous 3/4 patch into 2/4 patch
- used *_bulk API's
- re-wrote at91_for_each_port
- use dev_read_u32_default for pdata->ports
