[PATCH 1/3] lib: sbi_irqchip: Add irqchip private context pointer in sbi_irqchip_device

[Raymond Mao]

From: Raymond Mao <raymond.mao at riscstar.com>

HW specific private data is required for irqchip device operations,
for example, for APLIC, address, num_idc and num_source are needed
for mask / unmask / claim an IRQ, thus it is reasonable to add a
private HW data pointer in sbi_irqchip_device.
