drivers/intel: Add support for configurable footer logo bottom margin

Browse source 
Introduces logo_bottom_margin to soc_intel_common_config to allow
adjusting the vertical (or horizontal, based on orientation) offset of
the footer logo from the screen edge. This provides flexibility for
OEM branding placement.

BUG=b:423591644
TEST=Able to show OEM splash screen on google/fatcat.
