Simon Glass 86ee14f58b x86: Use the existing stack when chain-loading
With chromebook_coral we normally run TPL->SPL->U-Boot. This is the
'bare metal' case.

When running from coreboot we put u-boot.bin in the RW_LEGACY portion
of the image, e.g. with:

   cbfstool image-coral.serial.bin add-flat-binary -r RW_LEGACY \
	-f /tmp/b/chromebook_coral/u-boot.bin -n altfw/u-boot \
	-c lzma -l 0x1110000 -e 0x1110000

In this case U-Boot is run from coreboot (actually Depthcharge, its
payload) so we cannot access CAR. Use the existing stack instead.
