ApexQ: cycle bluetooth properly

hardware/qcom/bt/libbt-vendor assumes the hciattach daemon will properly
start upon setting bluetooth.hciattach=true on qcwcn targets, and reads
bluetooth.status 100 times, as this is the signal that hciattach has
successfully run. It takes about 8 seconds for this process to time out.
  On ApexQ, a substitute for hciattach runs only once on boot to
initialize the bt firmware. This change sets bluetooth.status to true
immediately, therefore, as hciattach is not going to be run, and
prevents the system from repeatedly querying the status before giving up
and enabling bluetooth anyway.
