efi: Set feature flags inside feature init functions
It makes more sense to set the feature flag in the success path of the detection function than it does to rely on the caller doing it. Apart from it being more logical to group the code and data together, it sets a much better example for new EFI architectures. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
