ChromeOS: Remove remnants of FDT support 

Originally, on ChromeBooks, coreboot would provide a modified
u-boot device tree (FDT) to u-boot in CBMEM. However, u-boot
can now create all the information it needs from the coreboot
table and add it to its device tree itself. This means we can
drop this (anyways unused) code.
