kernelci.org started detecting new boot failures for the mt8135-evb in
the arm-soc tree[1], and the boot failures were bisected down to this
patch, which landed upstream in the form of commit d186a394bb98 (ARM:
dts: mt8135: enable basic SMP bringup for mt8135)

Maybe this new SMP support requires updating the firmware on the board
as well?  If so, the changelog should've been a bit more explicit
about firmware dependencies.
