[ Upstream commit 7279d9917560bbd0d82813d6bf00490a82c06783 ]
men_z127_debounce() tries to round up and down, but uses functions which
are only suitable when the divider is a power of two, which is not the
case. Use the appropriate ones.
Found by static check. Compile tested.
Fixes: f436bc2726c64 ("gpio: add driver for MEN 16Z127 GPIO controller")
