power: supply: sysfs: Move power_supply_show_enum_with_available() up

Browse Source 
Move power_supply_show_enum_with_available() higher up in
the power_supply_sysfs.c file.

This is a preparation patch to avoid needing a forward declaration
when replacing power_supply_show_usb_type() with it later on.

This commit only moves the function, there are no changes to it.
