[PATCH 1/1] mfd: core: Fix memory leak of 'cell'

[Lee Jones]

When creating a platform device from an MFD cell description, we
allocate some memory and make a copy which is then stored inside the
platform_device's structure.  However, care is not currently taken to
free the allocated memory when the platform device is torn down.

This patch takes care of the leak.
