video: Add mDNIe colour and brightness control
https://github.com/AndreiLux/Perseus-UNIVERSAL5410/commit/01a54fed3aa9c950d8f25b09ccda1caea648324e

With these patches:
1.mDNIe-control AMS499QP01 master calibration
  https://github.com/AndreiLux/Perseus-UNIVERSAL5410/commit/44160aa329076c3ea5e1715a7f4db8b77c892a84

2.mDNIe-control: Add anti-smearing workaround
  https://github.com/AndreiLux/Perseus-UNIVERSAL5410/commit/d7bb254dc62ab20ca724590fb9412d500cc6a3f9
  This adds a single control for the black RGB channels and exempts those controls from the digital brightness control.

3.Make SCR controls absolute
  https://github.com/AndreiLux/Perseus-UNIVERSAL5410/commit/a0d9f0d324074479cf75538debdfaa242305aa1e

4.Fix master switches
  https://github.com/AndreiLux/Perseus-UNIVERSAL5410/commit/8bdd41fb23d645885dcbef97718c86ccb0864865
  That last commit was apparently stupid regarding absolute values on one byte registers.
