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.
