i2c: ocores: Move system PM hooks to the NOIRQ phase

SiFiveHolland · wsakernel · commit 382561d16854 · 2023-11-13T12:43:42.000-05:00
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.
