Upstream is migrating device trees like those of the am33xx to use simple-pm-bus, where applicable. These are buses that reference a clock or a power domain that needs to be enabled in order to use devices on it. As we didn't yet support this binding, this broke the Beaglebone and all other am33xx board since v2021.02.0. Fix this by adding simple-pm-bus to the of_default_bus_match_table. Note that this is only an adequate solution for when the power domain and clocks referenced are already enabled prior to barebox startup. For all other cases, driver support must be available for the clock and power domains in questions and this driver must be extended to make use of them. For the am33xx, the relevant buses are powered and clocked on boot up, so we leave general support to another day..
