LF-842-2: dt-bindings: display/bridge: nwl-dsi: Document video_pll clock

Add documentation for a new clock 'phy_parent'. This clock is optional
and is used to re-parent the PHY related clocks (phy_ref, tx_esc and
rx_esc) to a valid parent. This clock is needed, in order to make the
re-parenting in driver, since the default re-parenting in dts node
(using assigned-clock-parents) may break the LVDS block, which has it's
PHY shared with MIPI-DSI.
