gpiolib: acpi: Only trigger ActiveBoth interrupts on boot

Commit ca876c7483b6 ("gpiolib-acpi: make sure we trigger edge events at
least once on boot") introduced logic to trigger edge-based GPIO
interrupts during initialization to ensure proper initial state setup
when firmware doesn't initialize it.

However, according to the Microsoft GPIO documentation, triggering GPIO
interrupts during initialization should only happen for interrupts
marked as ActiveBoth (both IRQF_TRIGGER_RISING and IRQF_TRIGGER_FALLING)
and only when the associated GPIO line is already asserted (logic level
low).

The current implementation incorrectly triggers:
1. Any edge-triggered interrupt (RISING-only or FALLING-only)
2. RISING interrupts when value is high and FALLING when value is low

This causes problems at bootup for single-edge interrupts that
don't follow the ActiveBoth pattern.

Fix this by:
- Only triggering when BOTH rising and falling edges are configured
- Only triggering when the GPIO line is asserted (value == 0)
