[igt-dev] [PATCH i-g-t] tests/kms_chamelium: Add support to validate YUV pixel formats

[Kunal Joshi <kunal1.joshi@intel.com>]

Currently, only hard coded pixel formats are validated which are not
generic for all the platforms which leads to false alarms.
Added support to validate only those pixel formats which are supported
by platform.
