[PATCH v2 0/5] Kesytone II USB support

[WingMan Kwok]

Here is the updated version of the series which addresses comments from
earlier version [1].  The PHY register programming is moved to a separate
PHY driver.

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.

All three patches are posted together just for completeness. Only first patch
is expected to go via usb tree and other two via linux-keystone tree.

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