The original implementation used level detection for the first interrupt
after device reset to avoid potential interrupt line noise and missed
interrupts during the initialization phase. However, this approach
introduced unintended side effects when tested with certain touch panels,
including:
 - Delayed hardware interrupt response
 - Multiple spurious interrupt triggers

Switching back to edge detection for the first interrupt resolves these
issues while maintaining reliable interrupt handling.

Extensive testing across multiple platforms with touch panels from
various vendors confirms this change introduces no regressions.
