[PATCH v2 1/2] dt-bindings: phy: qca,ar7100-usb-phy: add AR9340, QCA9550 and the analog reset

[Rosen Penev <rosenp@gmail.com>]

From AR934x on, the analog part of the USB PHY has its own reset,
which has to be released along with the PHY one. Add it as a third,
optional reset, and add compatibles for AR934x and QCA955x, which need
it.
