[PATCH v2] docs: driver-api: device-io: Split out relaxed access mention

[Andrew Davis]

We list all the normal non-relaxed device io functions first, but also
list just the "read" versions of the relaxed device io functions.
Instead of adding the "write" versions to that list, fix a statement
below which should describe the relaxed versions so it is understood
that both read and write have relaxed versions.
