msm: camera: common: Change shutdown sequence for subdevices

Browse Source 
In subdev close call if CRM is still active wait for shutdown
from CRM [media device]. Remove subdevice check for active
handles, shutdown to happen irrespective of any active context.

If CRM is not active, subdevice shutdown should ensure there is
no access to kernel allocated buffers since at this point
memmgr is de-initialized.

As part of ICP close, remove usage of HFI queues, trigger PIL
to transfer FW memory ownership back to HLOS and power off ICP.
