Currently, the instance_post_init calls are performed from the leaf
class and all the way up to Object. This is incorrect because the
leaf class cannot observe property values applied by the superclasses;
for example, a compat property will be set on a device *after*
the class's post_init callback has run.
In particular this makes it impossible for implementations of
accel_cpu_instance_init() to operate based on the actual values of
the properties, though it seems that cxl_dsp_instance_post_init and
rp_instance_post_init might have similar issues.
Follow instead the same order as instance_init, starting with Object
and running the child class's instance_post_init after the parent.
