ARM: dts: msm: Limit max speed to High speed mode for msmtitanium

Limit max speed of USB operation to high speed only as seeing
issue with QMP PHY if superspeed mode is enabled during connect/
disconnect. Hence limit to high speed mode till issue is resolved.
Also remove AHB2PHY base address as AHB2PHY_TOP_CFG register access
is failing during reboot tests.

Also update USB master ID correctly for bus voting. Otherwise
bus voting registration fails.
