[PATCH v2 0/2] gpio: drop bitmap_complement() where feasible

The gpio drivers reproduce the following pattern:

bitmap_complement(tmp, data1, nbits);
bitmap_and(dst, data2, tmp, nbits);

This can be done in a single pass:

bitmap_andnot(dst, data2, data1, nbits);

v1: https://lore.kernel.org/all/20260417033439.318930-1-ynorov@nvidia.com/
v2:
- cleanup typos (Michal);
- split per individual drivers (Andy).
