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.

Add a 32-bit unique ID to plic, aplic, and imsic data which can be
used to differentiate multiple irqchip devices.

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.

This avoids needing to map a hartid to a hart index.

We update irqchip drivers makefile to use kconfig for enabling/disabling
drivers. To avoid compile errors, we also enable appropriate irqchip
drivers for each platform.

We add simple IMSIC library which is independent of hardware description
format (FDT or ACPI). This IMSIC library can be used by custom OpenSBI
platform support to setup IMSIC for external interrupts.
