Baolin Wang f78c55e3b4 power: reset: sc27xx: Allow the SC27XX poweroff driver building into a module
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.

Baolin Wang 274afbc3ad power: reset: sc27xx: Change to use cpu_down()
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().

Sherry Zong 6cdd5b09cb power: reset: sc27xx: Power off the external subsystems' connection
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.

Colin Ian King 93619fdec9 power: reset: make function sc27xx_poweroff_shutdown static
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?

Baolin Wang 3f5faf3a06 power: reset: Add Spreadtrum SC27xx PMIC power off support
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.
