Hi all,

This series adds more USB4 v2 features. First it makes the bandwidth
reservation to comply with the v2 connection manager guide, adds the
PMPS packet support bit and enables asymmetric 120/40G switching to
support the Ultra-High Bitrate DisplayPort modes.

Applies on top of the cleanup series I sent out this week [1].
