To support different handlers for different types of resets, we are
adding a sbi_list of restart handlers.
Instead of sbi_system_reset_set_device we use
sbi_system_reset_add_device to reflect the actual meaning.

Instead of having system_reset_check() and system_reset() callbacks
in platform operations, it will be much simpler for reset driver to
directly register these operations as a device to the sbi_system
implementation.

To implement the SBI SRST extension, we need two platform operations
for system reset:
1) system_reset_check() - This operation will check whether given
reset type and reason are supported by the platform
2) system_reset() - This operation will do the actual platform
system reset and it will not return if reset type and reason
are supported by the platform
This patch updates system reset related code everywhere as-per above.

We can now use the standard SBI SRST extension reset types instead
of the opensbi specific (SBI_PLATFORM_RESET_xyz) reset types hence
remove related opensbi specific defines. The "platform_" prefix of
the reset type parameter of sbi_system_reset() function should also
be removed.

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.

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.

This patch adds system-level early_exit and final_exit APIs
with corresponding platform hooks. These new APIs will be
primarily used by sbi_exit() in OpenSBI exit path.

We simplify early_init() and final_init() callbacks of sbi_platform
by removing "hartid" parameter.

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.
