This series adds support for programmable gamma modes and exposes a property interface for the same. Also added, support for multi segment gamma mode introduced in ICL+
It creates 2 property interfaces : 1. GAMMA_MODE_CAPS: This is immutable property and exposes the various gamma modes supported and the lut ranges. This is an enum property with element as blob id. Getting the blob id in userspace, user can get the mode supported and also the range of gamma mode supported with number of lut coefficients. 2. GAMMA_MODE: This is for user to set the gamma mode and send the lut values for that particular mode. v2: Used Ville's design and approach to define the interfaces. Addressed Matt Roper's review feedback and re-ordered the patches.
