[PATCH 2/5] rsi: add hci detach for hibernation and poweroff

[Siva Rebbagondla <siva8118@xxxxxxxxx>]

From: Siva Rebbagondla <siva.rebbagondla@xxxxxxxxxxxxxxxxxx>

As we missed to detach HCI, while entering power off or hibernation,
an extra hci interface gets created whenever system is woken up, to
avoid this we added hci_detach() in rsi_disconnect(), rsi_freeze(),
and rsi_shutdown() functions which are invoked for these tests.
This patch fixes the issue
