irqchip/sifive-plic: Fix chip_data access within a hierarchy
The plic driver crashes in plic_irq_unmask() when the interrupt is within a
hierarchy, as it picks the top-level chip_data instead of its local one.
Using irq_data_get_irq_chip_data() instead of irq_get_chip_data() solves
the issue for good.
Fixes: f1ad1133b18f ("irqchip/sifive-plic: Add support for multiple PLICs")
