drm/i915/uc: Update HuC firmware naming convention and load latest HuC

Make both GuC and HuC to use "." as the separator. Hardcode
the separator in MAKE_UC_FW_PATH. Remove the usage of "ver" from HuC.

The current convention being:
<platform>_<g/h>uc_<major>.<minor>.patch.bin

Update the versions of HuC being loaded of the platforms.

SKL - v2.0.0
BXT - v2.0.0
KBL - v4.0.0
GLK - v4.0.0
CFL - KBL v4.0.0
ICL - v9.0.0
CML - v4.0.0

v2: Remove the separator parameter altogether from
__MAKE_UC_FW_PATH.(Daniele)
- Squash all firmware update patches (Daniele)
v3: s/huc/HuC
- Correct the order of platforms
- Change REVID of cml to 5(Michal)
- Code space changes in huc_def (Daniele)
