power: supply: core: move power_supply_attr_group into #ifdef block
When building with CONFIG_SYSFS=n, the build error below is triggered:
ld: drivers/power/supply/power_supply_core.o:(.data+0x0): undefined
reference to `power_supply_attr_group'
The problem is that power_supply_attr_group is needed in
power_supply_core.c but defined in power_supply_sysfs.c, which is only
targeted with CONFIG_SYSFS=y. Therefore, move the extern declaration into
the #ifdef block that checks for CONFIG_SYSFS, and define an empty static
const struct otherwise. This is safe because the macro __ATRIBUTE_GROUPS in
power_supply_core.c will expand into an empty attribute_group array.
When building without CONFIG_SYSFS, there is an error because of a
recent refactoring that failed to update the stub of
power_supply_init_attrs():
drivers/power/supply/power_supply_core.c: In function 'power_supply_class_init':
drivers/power/supply/power_supply_core.c:1630:9: error: too few arguments to function 'power_supply_init_attrs'

drivers/power/supply/power_supply.h:25:20: note: declared here

| ^~~~~~~~~~~~~~~~~~~~~~~
Update the stub function to take no parameters like the rest of the
refactoring, which resolves the build error.
power: supply: bq27xxx: Report charge full state correctly
When reporting the charging status, the existing code reports the battery
as full only when the reported current flowing is exactly 0mA, which is
unlikely in practice.
Fix the reporting by giving priority to the battery's full state
indication/flag.
power: reset: rmobile-reset: Make sysc_base2 local
The static global variable sysc_base2 is no longer used outside the
probe method and the reset handler, so it can be converted to a local
variable, and passed to the reset handler via its callback data.
power: supply: core: constify the struct device_type usage
Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the
power_supply_dev_type variable to be a constant structure as well, placing
it into read-only memory which can not be modified at runtime.
In order to accomplish that, export power_supply_attr_group in
power_supply.h and use it with the macro __ATTRIBUTE_GROUPS when defining
power_supply_dev_type in power_supply_core.c. Therefore the attribute group
is no longer static. Lastly, because power_supply_attr_groups is no longer
dynamically associated to power_supply_dev_type in
power_supply_init_attrs(), make the function receive zero arguments.
