power: supply: cpcap-charger: include missing <linux/property.h>

This file uses dev_fwnode() without including the proper header for it,
relying on transitive header inclusion from:

drivers/power/supply/cpcap-charger.c
- include/linux/phy/omap_usb.h
  - include/linux/usb/phy_companion.h
    - include/linux/usb/otg.h
      - include/linux/phy/phy.h
        - drivers/phy/phy-provider.h
          - include/linux/of.h
            - include/linux/property.h

With the future removal of drivers/phy/phy-provider.h from
include/linux/phy/phy.h, this transitive inclusion would break.
