recipes-kernel/linux/*: Standardize use of KERNEL_FEATURES_INTEL_COMMON

Previously, some recipes hard set it to empty, and some recipes did not
set it at all. So in some cases, it acted like a global variable you
could modify, and in others you could only append to it. This behavior
made it difficult to use (which I doubt anyone was doing).

This patch changes the variable to be soft set to empty across all
recipes. This way it can be used to globally change meta-intel kernels
through a conf file, or individually in the different versioned recipes
should the need arise.
