baytrail: fix fadt structure for gpe0 block
The gpe0 block's size was being misreported. Correct
the gpe0 size and use make the FADT fields be more
robust instead instead of hand calculating fields that
are the based on the same size.
This change correctly enables GPE events in the kernel.
Confirmed this by using iotools read the gpe_cnt register.
BUG=chrome-os-partner:23505
BRANCH=None
TEST=Built and booted. Confirmed EC's GPE event is enabled (but
still not working).
