soc/intel/tigerlake: Remove redundant code from graphics.c

It looks like kernel was relying on BIOS setting DDI_A_4_LANES
when it was doing the max lane calculation if platform has older
graphics

With newer graphics, portA and portE no longer seem to share the
lanes. Hence, kernel assumes that eDP is using 4-lanes. So kernel
driver for these platforms relies on BIOS setting DDI_A_4_LANES
for it.Hence removing this code from coreboot

BUG=b:150788968
BRANCH=None
TEST=checked jslrvp and tglrvp compilation and boot.
