chromeos: Pass pointer to ChromeOS ACPI structure instead of VB Shared Data
coreboot used to pass some information to u-boot in the coreboot table and other information in a modified flat device tree. Since the FDT code was never upstreamed and removed from our tree, u-boot was changed to get the information it needs from the coreboot table alone. However, in the process of this change only the vboot shared data structure was passed on by coreboot, so when u-boot tried to update the ChromeOS specific ACPI entries, it would accidently overwrite the vboot data. This patch passes on the ChromeOS specific ACPI data structure instead of the vboot shared data. Another change to u-boot will teach it how to get to the vboot shared data from there.
