perf: qcom_l2_pmu: move to use request_irq by IRQF_NO_AUTOEN flag

request_irq() after setting IRQ_NOAUTOEN as below
irq_set_status_flags(irq, IRQ_NOAUTOEN); request_irq(dev, irq...); can
be replaced by request_irq() with IRQF_NO_AUTOEN flag.

this patch is made base on "add IRQF_NO_AUTOEN for request_irq" which
is being merged: https://lore.kernel.org/patchwork/patch/1388765/Signed-off-by: Tian Tao <tiantao6@hisilicon.com>
