[meta-intel] [PATCH 2/2] meta-intel.inc: allow disabling of Intel microcode

[nitin.a.kamble at intel.com]

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

As per request from Tom, allow disabling of the Intel microcode
feature for meta-intel BSPs.

If one adds this line to local.conf while build a meta-intel BSP,
the microcode feature will be disabled for the build target.

DISABLE_INTEL_MICROCODE = "1"
