Remove outdated display bounds calculation

Since the display info computed by updateDisplayAndOrientation
will be sent to setDisplayInfoOverrideFromWindowManager, the
logicalWidth and logicalHeight are already the same as the
configuration bounds. So the removed code (mainly from commit
338374) are almost no-op or just produce a wrong intermediate
state and will be replaced with correct value immediately.
