Bluetooth: Change page scan interval in fast connectable mode

This patch is based on a user space (hciops) patch which never made it
upstream but does make sense to include in the mgmt part of the kernel.

(User space) commit message from Dmitriy Paliy:
"
Page scan interval in fast connectable mode is changed from 22.5 msec to
160 msec to perform less aggressive page scanning. This is done
accordingly to controller vendor recommendation.

Primary concern is that current parameters 22.5 interval, 11.25 window,
and interleaved scanning occupy whole radio bandwidth. Changing interval
to 160 msec should be sufficient for both speeding up connection
establishment and leaving space for other activities, like inquiry scan,
e.g.
