Bluetooth: hci_intel: Fix firmware file name to use hw_variant
The format of Intel Bluetooth firmware for bootloader product is
ibt-<hw_variant>-<device_revision_id>.sfi and .ddc.
This patch uses a hw_variant value read from the device during
runtime to form the firmware filenames instead of using a constant
value, so it can support multiple prouducts.
