i2c: ocores: use request_any_context_irq() to register IRQ handler
The i2c-ocores device is an HDL component that get instantiated in FPGA. The software stack used to drive an FPGA can be very different, and the i2c-ocore ip-core must work in different context. With respect to this patch the IRQ controller behind this device, and its driver, can have different implementations (nested threads). For this reason, it is safer to use `request_any_context_irq()` to avoid errors at probe time.
