lib: utils/irqchip/imsic: embed sbi_irqchip_device in imsic data

Browse Source 
Embed sbi_irqchip_device in struct imsic_data to enable instance-based
irqchip registration, replacing the previous global imsic_device
singleton. Include sbi_irqchip.h from imsic.h to make the embedded
struct visible to consumers.
