There is an extra amount of overhead being adding to XHCI HCD removal
cases when the HCD needs to undergo a runtime resume. The xhc_reinit
logic will attempt to restart the HC if there is a HCE observed during
resume. However, in the removal case, this is not required as the
XHCI stop/halt will execute the same operations. In addition, it isn't
needed that the HC be placed back into the running state if it is being
removed.
Changes in v3:
- Update xhci-plat to set the removal flag before issuing the runtime PM
get
Changes in v2:
- Fixed spacing issue
