With "cgroup: Use kernel command line to disable memory cgroup" merged to RPi
kernel as 86099de [1], the device tree now contains "cgroup_disable=memory"
parameter. The parameters are parsed in the order defined in the cmdline and
with the previous order, the memory CG ends up disabled. Switching the order
fixes that and makes the order similar to what we get with standard bootloader
and parameters in cmdline.txt only.
The possible downside is that it won't be possible to override parameters from
hardcoded bootargs_hassos using cmdline.txt anymore, however, it's unlikely any
of these parameters will need to be adjusted by users.
Fixes #3765
