x86: geode: Mark mfgpt irq IRQF_TIMER to prevent resume failure
Timer interrupts are excluded from being disabled during suspend. The clock events code manages the disabling of clock events on its own because the timer interrupt needs to be functional before the resume code reenables the device interrupts. The mfgpt timer request its interrupt without setting the IRQF_TIMER flag so suspend_device_irqs() disables it as well which results in a fatal resume failure. Adding IRQF_TIMER to the interupt flags when requesting the mrgpt timer interrupt solves the problem.
