[PATCH v4 0/2] Kesytone II USB host and PHY drivers

[WingMan Kwok]

Resending the series with suggested minor updates from v3 [1].

Series adds USB host support for Keystone SOCs. Keystone SOCs
uses dwc3 hardware IP implementation.  On Keystone II platforms,
we use no-op phy driver.

Patchset are tested on Keystone II EVM with USB2.0 and USB3.0
flash drives along with dts changes.
