mb/dell/snb_ivb_latitude: Move early_init.c out of variants

Now that the USB configs are in the devicetree, only the
bootblock_mainboard_early_init function remains in early_init.c. It is
identical between every variant except the E6230, which enabled fewer
decode ranges in the LPC_EN register. Enabling the additional decode
ranges probably shouldn't cause issues, so go with the majority.

TEST=Timeless builds do not change with the exception of the E6230.
