i2c: ocores: Move system PM hooks to the NOIRQ phase
When an I2C device contains a wake IRQ subordinate to a regmap-irq chip,
the regmap-irq code must be able to perform I2C transactions during
suspend_device_irqs() and resume_device_irqs(). Therefore, the bus must
be suspended/resumed during the NOIRQ phase.
