lib: utils: Fix irqchip registration for PLIC and APLIC

Browse Source 
Currently, the same irqchip instance is registered for multiple PLIC
and APLIC instances which causes the sbi_list_for_each_entry() loop
in the sbi_irqchip_init() to hang at boot-time.

To address the above issue, register a separate irqchip instance for
each PLIC and APLIC instance.

Fixes: 2dd6eaf680 ("lib: sbi_irqchip: Call driver warm_init from SBI core")
