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.

EHCI: HSIC: Fix GPT timer count values used for resume sequence

The counter value to be loaded into GPT timer represents the time
in micro seconds minus 1 for the timer duration.  The current code
incorrectly programs the timer.  Fix it.

cpufreq: interactive: Fix blocked task warnings

Running a kernel that never enables the interactive cpufreq
will eventually hit the following warning:

INFO: task kinteractiveup:112 blocked for more than 120 seconds.
kinteractiveup  D c07ae3a4  7072   112      2 0x00000000
[<c07ae3a4>] (__schedule+0x4e4/0x5c4) from [<c00a1b8c>] (kthread+0x70/0x94)
[<c00a1b8c>] (kthread+0x70/0x94) from [<c000f368>]
(kernel_thread_exit+0x0/0x8)

due to the fact that the kthread is never woken up after being
forked. Kick the thread to its idle loop so that it can
schedule() and move out of the D state.
