gpio: Fix wrong rounding in gpio-menz127
[ Upstream commitpull/10/head7279d99175
] 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:f436bc2726
