Bluetooth: bluecard: blink LED during continuous activity

Browse Source 
Currently the activity LED is solid on during continuous activity.
Blink the LED during continuous activity to match Windows driver
behavior.

Cards with activity LED:
power LED = solid on when up, off when down
activity LED = blinking during activity, off when idle

Cards without activity LED:
power LED = solid on when up, off when down, blinking during activity
(don't have such a card so I don't know if Windows driver does the same
thing)
