irqchip: gic-pm: Use pm_runtime_resume_and_get() in gic_probe() 

Bugzilla: https://bugzilla.redhat.com/2114045

    irqchip: gic-pm: Use pm_runtime_resume_and_get() in gic_probe()

    gic_probe() calls pm_runtime_get_sync() and added fail path as
    rpm_put to put usage_counter. However, pm_runtime_get_sync()
    will increment usage_counter even it failed. Fix it by replacing it with
    pm_runtime_resume_and_get() to keep usage counter balanced.

    Fixes: 9c8edddfc9 ("irqchip/gic: Add platform driver for non-root GICs that require RPM")
