Although "https://www.nxp.com" hosts Rev 7 (2021) of this specification, it is behind a login-wall. Thus, an additional link has been added (which doesn't require a login) and the NXP official docs link has been updated.

Provide its description and replace start ("S") conditions with repeated start ("Sr") conditions when relevant. This allows the documentation to match the SMBus specification available at [1].
