[PATCH v2 phy-next 16/24] drm: bridge: cdns-mhdp8546: use consumer API for getting PHY bus width

[vladimir.oltean@nxp.com]

The Cadence MHDP8546 DP bridge driver gets the PHY bus_width attribute
(holding number of lanes) directly, but doing this will no longer be
possible after the definition of struct phy is hidden from consumers.

Use the phy_get_bus_width() API function designed specifically for
consumers.
