ath10k: qmi: Sleep for a while before assigning MSA memory
Unless we sleep for a while before transitioning the MSA memory to WLAN the MPSS.AT.4.0.c2-01184-SDM845_GEN_PACK-1 firmware triggers a security violation fairly reliably. Unforutnately recovering from this failure always results in the entire system freezing. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
