[ Upstream commit 3285170f ]

Commit 372e722e ("gpiolib: use descriptors internally") renamed
the functions to use a "gpiod" prefix, and commit 79a9becd
("gpiolib: export descriptor-based GPIO interface") introduced the "raw"
variants, but both changes forgot to update the comments.

Readd a similar reference to gpiod_set_value(), which was accidentally
removed by commit 1e77fc82 ("gpio: Add missing open drain/source
handling to gpiod_set_value_cansleep()").
