mfd: sm501: Fix potential memory leaks during remove
commit 83feedd9d83c0c5199f98c72df0a6196b4aefb4d upstream.
The memory allocated for struct sm501_devdata in sm501_pci_probe() and
sm501_plat_probe() is not freed by the corresponding remove functions
sm501_pci_remove() and sm501_plat_remove(). Fix that by adding a call to
kfree().
