[PATCH v3 0/2] Kesytone II USB host and PHY drivers

[WingMan Kwok]

Here is the updated version of the series which addresses comments from
earlier version [1]. The lock in the isr is removed as per the discussion.

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.
