remoteproc: ingenic: Request IRQ disabled
The ingenic remoteproc driver requests its IRQ and then immediately disables it. The disable is necessary since irq_request() normally enables the IRQ. But there is a new flag IRQF_NO_AUTOEN that when specified keeps the IRQ disabled. Use this new flag rather than calling disable_irq(). This slightly reduce the boilerplate code and also avoids a theoretical race condition where the IRQ could fire between irq_request() and disable_irq().
