ARM: bcm: Add missing sentinel to bcm2711_compat[] commit 781fa0a95424 ("ARM: bcm: Add support for BCM2711 SoC") breaks boot of many other platforms (e.g. OMAP or i.MX6) if CONFIG_ARCH_BCM2835 is enabled in addition to some multiplatform config (e.g. omap2plus_defconfig). The symptom is that the OMAP based board does not show any activity beyond "Starting Kernel ..." even with earlycon. Reverting the mentioned commit makes it work again. The real fix is to add the missing NULL sentinel to the bcm2711_compat[] variable-length array.
