/*
 * This test case is designed to test the hardware timer driver.
 * It will:
 * 1. Find two hardware timer devices.
 * 2. Open both devices.
 * 3. Set a custom frequency for timer0 and use the default frequency for timer1.
 * 4. Start both timers with different timeout values.
 * 5. Poll and print the current value of each timer every second.
 * 6. Trigger the interrupt callback when the timer times out and print a message.
