EHCI: HSIC: Fix a race between root hub resume and controller removal
The pm_qos request is removed before unregistering the HCD in remove
function. If root hub resume runs in parallel, there is a possibility
of adding the pm_qos request back to the active list. The pm_qos request
memory is freed after unregistering the HCD and this would lead to
pm_qos list corruption. A crash is observed when another driver is
submitting a pm_qos request after HSIC controller is removed during
shutdown. Remove HCD prior to releasing controller resources.
