acpi: fix FADT header version for ChromeOS devices

Haswell, Broadwell, Baytrail, and Braswell ChromeOS devices'
FADT version were incorrectly set to 3, rather than the correct
ACPI_FADT_REV_ACPI_3_0. The incorrect value resulted in these
devices reporting compliance to ACPI 2.0, rather than ACPI 3.0.

This mirrors similar recent changes to SKL and APL SoCs.

Test: boot any affected device and check ACPI version reported
vai FADT header using OS-appropriate tools.
