tenderloin usb: fix release of wakelock

The msm_otg wakelock can get 'stuck' in some cases. In particular,
when Touchpad is placed on Touchstone charger when the Touchpad
is in deep-sleep. This should allow for proper release of the
msm_otg wakelock in that and similar cases.
tenderloin defconfig: disable USB_MSM_ACA

The MSM_ACA code can conflict with the multiple charger detection
and USB Downstream Charging ports.

* also reenable MSM_OTG
