[U-Boot] [PATCH v9 00/11] Add support for DM_USB and DM_USB_DEV for TI's DRA7 EVMs and AM57 EVMs platforms.

[Jean-Jacques Hiblot]

This series applies on top of the series "[PATCH v4 0/10] Improvements for
the dwc3_generic driver"
The branch is also available on github:
https://github.com/jjhiblot/u-boot/tree/dm_usb_dra7_v9

Moving to DM_USB and DM_USB_DEV brings some benefits:
- it is required to support DM_ETH and USB network adapters with the same
  binary.
- support for USB3 on AM57x comes almost for free
- removal of platform code related to USB

Tested on:
- dra76 evm
- AM572 evm

Changes in v9
- rebased on top of latest u-boot/master
- use DM_USB_GADGET instead of DM_USB_DEV
- remove edison build fix (move to the dwc3 series)

Changes in v8:
- Fix edison build

Changes in v7:
- replace remaining if() statements with ut_assert()
- Fix build issue "multiple definition of `usb_gadget_handle_interrupts'"
- Fixed build issue "multiple definition of `usb_gadget_handle_interrupts'"

Changes in v6:
- ti-pipe3-phy: take PLL out of IDLE in pipe3_init(). The PLL may have
  been put into idle by pipe3_exit()
- DRA7 configs: enable DM_USB and DM_USB_DEV. Use DWC3_GENERIC in place of
DWC3_OF_SIMPLE. disable non DM USB options
- AM57 configs: enable DM_USB and DM_USB_DEV. Use DWC3_GENERIC in place of
DWC3_OF_SIMPLE. disable non DM USB options
- Supports DM USB for peripherals
- Removed DTS changes that disabled USB1 on DRA7 because DM_USB_DEV is
  now supported

Changes in v5:
- Rebased on latest u-boot
- Removed patches that have already been merged

Changes in v4:
- Fix word missing in commit log
- Remove dependency on MISC
- Renamed the commit (DM_USB is already enabled, the only missing option
  is for the USB2 phy driver)
- Remove dependency on MISC
- Remove omap specific glue layer and use dwc3-of-simple glue layer

Changes in v3:
- in syscon_regmap_lookup_by_phandle(), use dev_dbg() instead of printf()
- added unit test for syscon_regmap_lookup_by_phandle()

Changes in v2:
- Add USB3 support to ti-pipe3-phy driver
- omap-usb2-phy: Implement power_on and power_off callbacks
- am57xx boards: when DM_USB is used, turn on the required USB clocks
- split dts changes in 2 commits: one for binding the children of
  ocp2scp at 4a080000, and one to disable USB1  on all DRA7 EVMs
- Enable DM_USB in am57xx_evm_defconfig. USB3 (super speed) is supported.
