[PATCH 1/4] ARM: cpu: board-dt-2nd: call arm_cpu_lowlevel_init

The generic DT image could be started by boot firmware that doesn't do
all the initialization that we do in arm_cpu_lowlevel_init(), so call it
always for good measure. This enables using the generic image as second
stage to the Raspberry Pi videocore.
