Bluetooth: btintel: Use boot parameter from firmware file

Each RAM SKU has a different boot parameter which is used in
HCI_Intel_Reset command after downloading the firmware.
The boot parameter is embedded in the firmware data and to support
multiple SKUs, driver reads the boot parameter while downloading
the firmware instead of using static values per SKU.
