Tables: Enable default 64-bit FADT addresses favor.
Browse files Browse the repository at this point in the history
With enough protections, this patch re-enables 64-bit FADT addresses by
default. If regressions are reported against such change, this patch should
be bisected and reverted.
Note that 64-bit FACS favor and 64-bit firmware waking vector favor are
excluded by this commit in order not to break OSPMs. Lv Zheng.
