commit 6dde43584f18 ("lib: utils/sys: Extend HTIF library to allow custom base address")
forgot to update do_tohost_fromhost() codes for RV32, which still
accesses the HTIF registers using the ELF symbol address directly.

Some of RISC-V emulators provide HTIF at fixed base address so for
such emulators users have to hard-code HTIF base address in the
linker script.
To address this problem, we let users optionally provide fixed HTIF
base address via platform support (or device tree).

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 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.
