The HCI spec defines the BIS index range as starting from
index 0x01. We had previously implemented it such that it
starts from 0x00, and then simply adding 1 to the index
when sending over HCI. However, this may cause issue with
other HCI, or other SIG defined specification, commands
and events, and thus it is probably simpler if we just
use the HCI defined range.
This commit disallows BIT(0) (representing the BIS
index 0x00) to be set, and removes the addition
of 1 when sending over HCI.
