[RFC PATCH 2/4] Bluetooth: hci_intel: add the CcP controller (hardware variant 0x14)

[Cai Yu <caiyu7372@gmail.com>]

The Intel CcP controller (hardware variant 0x14) is used on the
Lakefield and Jasper Lake platforms.  btintel_get_fw_name() in btintel.c
already knows it and builds the same three-part firmware name as for
ThP/JfP/HcP (intel/ibt-<hw_variant>-<hw_revision>-<fw_revision>), but
hci_intel.c duplicates that lookup and rejects the variant before the
firmware is requested:

  Bluetooth: hci0: Unsupported Intel hardware variant (20)

Add 0x14 to the variant check and to both firmware name switches.

Tested on a Lenovo ThinkPad X1 Fold Gen1 (Lakefield, ACPI INT33E4):
intel/ibt-20-1-3.sfi is requested and the DDC parameters are applied.
