mb/google/brya: disable early EC sync for nereid

Browse source 
The ITE EC used on Nereid can take a long time to update, and especially
too long to erase. There is a 1 second timeout enforced on the EC erase
command, but Nereid's IT81302 will typically take about 5 seconds to
complete erase, and could take as long as 30.

Since this affects any Nissa variant using an ITE EC and it's nice to
make the entire Nissa project consistent, this change disables early
sync for all Nissa boards.

BUG=b:222987250
TEST=EC software sync is no longer attempted (and thus does not fail) on
     Nereid.
