[meta-intel] [Patch v4 02/12] intel-ucode: a new MACHINE_FEATURE for meta-intel BSPs

[nitin.a.kamble at intel.com]

From: Nitin A Kamble <nitin.a.kamble at intel.com>

With this change, the Intel microcode support can be enabled or disabled
for any BSP by controlling the MACHINE_FEATURES variable.

Any BSP from meta-intel layer can enable the Intel microcode loading support
by adding the following line in the machine configuration.

MACHINE_FEATURES += "intel-ucode"

This change keeps the intel-microcode loading feature disabled by default,
and it is enabled as an "opt-in" feature using the MACHINE_FEATURES variable.
