Subject: [PATCH] BCM2711 reboot fix
According to the commit b334c1afad17132a3c2360de64c1cfff90908739 in Linux
kernel, the `compatible` string for the watchdog peripheral in the DTS was modified from
`brcm,bcm2835-pm` to `brcm,bcm2711-pm`, which caused
`rpi4_map_watchdog()` function to fail, leading to inability to reboot
the system under Xen hypervisor.
