This driver is confusing in referencing/dereferencing the global
GPIO number scope in some places and using local offsets in other
places. Remove some of the confusion by removing local "bit" and
"bitmask" definitions and just use BIT(offset) directly. Also
unexport a function only used in this file.

The range is registered into a linked list which can be referenced
throughout the lifetime of the driver. Ensure the range's memory is useful
for the same lifetime by adding it to the driver's private data structure.

The bug was introduced in the driver's initial commit, which was present in
v3.10.
