…for all cores.
The MPC is currently set up to allow R,W,X,Priv access to all RAM
and MRAM for all cores. This is not sufficient if CONFIG_USERSPACE
is enabled, in which case the application core will be accessing
memory unprivileged, using the MPU to manage memory access.
Update MPC configuration to allow R,W,X,Unpriv access to all RAM and
MRAM for all cores. The R,W,X MPC configuration has to be applied
regardless of CONFIG_USERSPACE, so no need to conditionally include
the MPU configuration based in CONFIG_USERSPACE.
