Run button_exti example on STM32H5 but a panic occurs

[joshuajylin]

I guess there's something wrong when MCU wakes up from the low-power mode.
I added button_exti into the stop example and everything worked fine.

cargo run --bin button_exti

I found that low_power::on_wakeup_irq() will be called if the low-power feature is enabled.
So I removed the low-power feature from embassy-stm32 in Cargo.toml and the button_exti example worked.
