The IRAM is part of the HiFi DSP.
According to hardware specification only 32-bits write are allowed
otherwise we get a Kernel panic.
Therefore add a custom memory copy and memset functions to deal with
the above restriction.
Which platform has this limitation? This driver has been landed for
quite some time, is there any specific condition to trigger the issue?

Peng.
Any platform with HiFi DSP.
As I explained in the previous version, until now, it was used in a
limited scenario and the firmware was correctly built to respect the
write restriction - having the IRAM sections size a multiple of 4bytes.
Now, I was trying a simple hello_world sample from Zephyr, compiled with
GCC and I crashed the Kernel trying to load it on the hifi4 DSP.
Thanks,
Iulia
