lib: sbi_irqchip: Call driver warm_init from SBI core
Currently, each platform keeps track of which irqchip driver is in use
and calls its warm init function. Since the generic platform may use
multiple irqchip drivers, it has logic to track an array of drivers.
The code is simplified and made common across platforms by treating warm
init and exit as properties of the driver, not the platform. Then the
platform's only role is to select and prepare a driver during cold boot.
For now, only add a .warm_init hook, since none of the existing drivers
need an .exit hook. It could be added in the future if needed.
