3e7e07c4cf drm/i915: Move the DPLL extra power domain handling up one level 
The extra DPLL power domain is currently handled in three places:
- combo_pll_enable()
- combo_pll_disable()
- readout_dpll_hw_state()

First two of those are low level PLL funcs, but the third is a higher
level thing. So the current situation is rather inconsistent. Unify
this by moving the PLL enable/disable up one level. This also means
the extra power domain could be trivially be used by other platforms
as well.

7e72cd6caf drm/i915: Abstract the extra JSL/EHL DPLL4 power domain better 
Just include the JSL/EHL DPLL4 extra power domain in the dpll_info
struct. This way the same approach could be used by other platforms
as well (should the need arise), and we don't have to sprinkle
platform checks all over the place.

Note that I'm perhaps slightly abusing things here as
power_domain==0 (which is actually POWER_DOMAIN_DISPLAY_CORE) now
indicates that no extra power domain is needed. I suppose using
POWER_DOMAIN_INVALID would be more correct, but then we'd have to
sprinkle that to all the other DPLLs.

f215038f41 drm/i915: Use named initializers for DPLL info 
Use named initializers when populating the DPLL info. This
is just more convenient and less error prone as we no longer
have to keep the initializers in a specific order.

9e372744c0 drm/i915/bios: Clamp VBT HDMI level shift on BDW 
Apparently some BDW machines (eg. HP Pavilion 15-ab) shipped with
a VBT inherited from some earlier HSW model. On HSW the HDMI level
shift value could go up to 11, whereas on BDW the maximum value is
9.

The DDI code does clamp the bogus value, but it does so with
a WARN which we don't really want. To avoid that let's just sanitize
the bogus VBT HDMI level shift value ahead of time for all BDW machines.
