Because this index is only needed when bandwidth >= 20 MHz, adjust order of enumerator bandwidth to access offsets array easier. To prevent misuse RTW89_CHANNEL_WIDTH_NUM as size, change it to RTW89_CHANNEL_WIDTH_ORDINARY_NUM that will be the size of array. The enumerator values of bandwidth (before ordinary number) will be also used by upcoming TX power table built in firmware file, so add a comment to remind keeping the order.
