By default bt_ad was setting just BT_AD_MAX_DATA_LEN (31) which is not
enough to handle devices advertising using EA, so this switches the
default to be BT_EA_MAX_DATA_LEN (251) since EA is much more common
nowadays and for those case where the it is not supported (e.g. for
advertisers without EA support) then shall be using bt_ad_set_max_len
to adjust the maximum length.
