soc/intel/alderlake: Add support to skip the MBP HOB
This patch adds the support to enable/disable skipping MBP HOB
from the devicetree based on mainboard requirement.
Only ADL-N FSP has the required support to skip the MBP HOB and
enabling it is saving the Boot time.
BUG=b:241850107
TEST=Build and boot to verify that the right value has been passed to
the FSP.
