[PATCH] remoteproc: qcom_q6v5_mss: Re-order writes to the IMEM region

[Sibi Sankar]

Any write access to the IMEM region when the Q6 is setting up XPU
protection on it will result in a XPU violation. Fix this by ensuring
IMEM writes related to the MBA post-mortem logs happen before the Q6
is brought out of reset.
Fixes: 318130cc9362 ("remoteproc: qcom_q6v5_mss: Add MBA log extraction 
support")
