config/coreboot: Add Dell Latitude E4300

Add patches to convert the E6400 port into a GM45 Latitude variant and
add the E4300 as another variant, and create a config for the E4300.
Tested on my E6400 and E4300.

+Subject: [PATCH 62/63] mb/dell: Convert E6400 into a variant
+
+All the GM45 Dell Latitudes should be nearly identical, so convert the
+E6400 port into a variant so that future ports for the other systems can
+share code with each other.
