Bluetooth: hci_intel: Update firmware filename for Intel 9x60 and later 

The format of Intel Bluetooth firmware for bootloader product is
ibt-<hw_variant>-<device_revision_id>.sfi and .ddc.

But for the 9x60 SKU, there are three variants of FW, which cannot be
differenticate just with hw_variant and device_revision_id.
So, to pick the appropriate FW file for 9x60 SKU, three fields,
hw_variant, hw_revision, and fw_revision, needs to be used rather than
hw_variant and device_revision_id.

Format will be like this:
ibt-<hw_variant>-<hw_revision>-<fw_revision>.sfi and .ddc

/* With this Intel bootloader only the hardware variant and device
* revision information are used to select the right firmware.
* revision information are used to select the right firmware for SfP
* and WsP.
*
* The firmware filename is ibt-<hw_variant>-<dev_revid>.sfi.
*
* Currently the supported hardware variants are:
* 11 (0x0b) for iBT 3.0 (LnP/SfP)
* 12 (0x0c) for iBT 3.5 (WsP)
*
* For ThP/JfP and for future SKU's, the FW name varies based on HW
* variant, HW revision and FW revision, as these are dependent on CNVi
* and RF Combination.
*
* 18 (0x12) for iBT3.5 (ThP/JfP)
*
* The firmware file name for these will be
* ibt-<hw_variant>-<hw_revision>-<fw_revision>.sfi.
