BUG: Fix AFIO bit clearing in set_remap_config

Previously, the mask operation in set_remap_config used `value &= mask << entry.start;`, which incorrectly kept unrelated bits and caused GPIO remapping to behave incorrectly.

This change updates it to `value &= ~(mask << entry.start);` so that only the intended bits are cleared before setting the new value.
