lib: Simplify sbi_platform irqchip_init() hooks

Browse Source 
Instead of having separate irqchip_init() hooks for cold and
warm boot, this patch updates struct sbi_platform to have just
one irqchip_init() hook. The type of boot (cold or warm) is now
a boolean flag parameter for the updated irqchip_init() hook.
