Anup Patel a9eac67ad0 include: sbi_platform: Combine reboot and shutdown into one callback
We can achieve shutdown, cold reboot, and warm reboot using just
one sbi_platform callback so we combine system_reboot() and
system_shutdown() callbacks into one system_reset() callback.

Anup Patel 15ed1e7452 lib: improve system reboot and shutdown implementation
We improve sbi_system_reboot() an sbi_system_shutdown() by:

1. Calling halt IPI to all harts (except current HART) before
   calling platform reboot/shutdown hook.
2. Calling sbi_exit() instead of sbi_hang() in-case platform
   reboot/shutdown hook failed.

Anup Patel 7b59571758 lib: Simplify sbi_platform early_init() and final_init() hooks
Instead of having separate early_init() and final_init() hooks
for cold and warm boot, this patch updates struct sbi_platform
to have just one early_init() and one final_init() hook. The
type of boot (cold or warm) is now a boolean flag parameter for
the updated early_init() and final_init() hooks.
