bluez5: initialize BT in HCI_H4 mode and disable IBS and DEEP_SLEEP on firmware binary 

Initialize Bluetooth chip in HCI_H4 mode and provide a firmware binary
with the IBS and DEEP_SLEEP mode disabled by default. Also this firmware
enables an internal clock required to maintain the system on low power modes.

Subject: [PATCH] bluetooth: Disable bluetooth low power mode functionality
In some conditions the low power modes cause communication
errors between the BT chip and the system, for this reason
we disable it by default.
