drm: Add HLG EOTF
ADD HLG EOTF to the list of EOTF transfer functions supported.
Hybrid Log-Gamma (HLG) is a high dynamic range (HDR) standard.
HLG defines a nonlinear transfer function in which the lower
half of the signal values use a gamma curve and the upper half
of the signal values use a logarithmic curve.
v2: Rebase
v3: Fixed a warning message
v4: Addressed Shashank's review comments
v5: Addressed Jonas Karlman's review comment and dropped the i915
tag from header.
