Which way is the right way to initialize embassy?

[yanshay]

In https://github.com/esp-rs/esp-hal/blob/v0.21.0/esp-hal-embassy/MIGRATING-0.3.md it shows:

esp_hal_embassy::init(timg0); // should really be timg0.timer0

And no mention for different initialization for different devices.

In the wifi_embassy_dhcp example the code is (for other than esp32)

let systimer = SystemTimer::new(peripherals.SYSTIMER).split::<Target>();
esp_hal_embassy::init(systimer.alarm0);

So what's the correct approach?
