[libgpiod][PATCH 3/6] treewide: rename BIAS_AS_IS to BIAS_NONE

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

When inspecting the current bias setting of a GPIO line, the AS_IS name
of one of the possible values really means that there's no bias so it
should be renamed to NONE for clarity.
