Supporting DM USB is required to support DM_ETH and USB network adapters
with the same binary.
This series adds support for DM_USB for the DRA7/AM57 families. As a bonus
it adds support for USB3.

This series applies on the usb tree with the following fixes:
-[PATCH] reset: fix bulk API when DM_RESET is disabled
-[PATCH] usb: dwc3-of-simple: fix error check of clk_get_bulk when disabled

limitation:
- only Host mode is supported. The Device mode can be added later.

Tested on:
- dra7 evm
- dra71 evm
- dra72 evm
- dra72 evm rev C
- dra76 evm
- AM572 evm

Changes in v4:
- Fix word missing in commit log
- Remove dependency on MISC
- Renamed the commit "configs: enable DM_USB for all the platforms of the DRA7 
family"
- 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@4a080000, and one to disable USB1  on all DRA7 EVMs
- Instead of disabling USB1 port in dts files, use *-u-boot.dtsi files
- Enable DM_USB in am57xx_evm_defconfig. USB3 (super speed) is supported.
