meta-intel: Add new intel-ucode MACHINE_FEATURE
With this change, Intel microcode support can be enabled or disabled for any BSP by controlling the MACHINE_FEATURES variable. Any BSP from the meta-intel layer can enable Intel microcode loading support by adding the following line in the machine configuration. MACHINE_FEATURES += "intel-ucode" This change keeps the intel-microcode feature disabled by default; it can however be enabled as an "opt-in" feature via the MACHINE_FEATURES variable.
