pmdomain: qcom: rpmpd: Set GENPD_FLAG_ACTIVE_WAKEUP

Browse Source 
Set GENPD_FLAG_ACTIVE_WAKEUP for all RPM power domains so that power
domains necessary for wakeup/"awake path" devices are kept on across
suspend.

This is needed for example for the *_AO ("active-only") variants of the
RPMPDs used by the CPU. Those should maintain their votes also across
system suspend to ensure the CPU can keep running for the whole suspend
process (ending in a firmware call). When the RPM firmware detects that
the CPUs are in a deep idle state it will drop those votes automatically.
