From: Sibi Sankar <quic_sibis@xxxxxxxxxxx> commit d2fab3fc27cbca7ba65c539a2c5fc7f941231983 upstream. The qcom-cpucp mailbox irq is expected to function during suspend-resume cycle particularly when the scmi cpufreq driver can query the current frequency using the get_level message after the cpus are brought up during resume. Hence mark the irq with IRQF_NO_SUSPEND flag to fix the do_xfer failures we see during resume.
