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. It
leverages the work done for the STi family.
This series applies on top of "xhci-dwc3: Couple of fixes for USB3 support"
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 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
- 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.

syscon_regmap_lookup_by_phandle() can be used to the regmap of a syscon
device from a reference in the DTS. It operates similarly to the linux
version of the namesake function.

The omap5 uses the dwc3. The dwc3 supports the driver model but it requires
some glue logic to load the the driver.

On all the EVMs featuring a SOC of the DRA7 family, the USB1 port is used
as a device for DFU. This port is managed by the platform code and must not
be advertised to the DWC3 DM driver.
This will be changed when/if support for the device mode is added to the
dwc3-omap driver.

Changes in v2:
- Instead of disabling USB1 port in dts files, use *-u-boot.dtsi files

Is it intentional to call omap_usb_phy_power() here ? as it is already
called in omap_usb2_phy_power_off().

It is just to make sure that the power is off, even if the power_off()
callback hadn't been called.
It is not really required, but it doesn't hurt.

Can you use -ENOENT or something else here? At present -ENODEV means
there is no device, which in fact we have a device (@dev). This can be
confusing since there are places in DM core where -ENODEV signals that
there was no device, and not to worry about it.
