mailbox: qcom-cpucp: Mark the irq with IRQF_NO_SUSPEND flag

Browse Source 
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.

Err Logs:
arm-scmi firmware:scmi: timed out in resp(caller:do_xfer+0x164/0x568)
cpufreq: cpufreq_online: ->get() failed
