Change the config to 'tristate' and use module_platform_driver() to
allow the SC27XX poweroff driver building into a module, as well as
adding some mudule information.

To allow the SC27XX driver can be built as a module, and the
freeze_secondary_cpus() symbol is not exported, thus we can change
to use the exported cpu_down() API to shut down other cpus to avoid
racing, which is same as the freeze_secondary_cpus().

When powering off the whole system, we should power off some external
subsystems' connection firstly, otherwise some external subsystems
will hold some power and result in powering down abnormally.

The function sc27xx_poweroff_shutdown is local to the source and does
not need to be in global scope, so make it static.
Cleans up sparse warning:
drivers/power/reset/sc27xx-poweroff.c:28:6: warning: symbol
'sc27xx_poweroff_shutdown' was not declared. Should it be static?

On Spreadtrum platform, we need power off system through external SC27xx
series PMICs including the SC2720, SC2721, SC2723, SC2730 and SC2731 chips.
Thus this patch adds SC27xx series PMICs power-off support.
