net: wan: framer: pef2256: Switch to devm_mfd_add_devices()

Browse source

[ Upstream commit 4d6ec3a793 ]

The driver calls mfd_add_devices() but fails to call mfd_remove_devices()
in error paths after successful MFD device registration and in the remove
function. This leads to resource leaks where MFD child devices are not
properly unregistered.

Replace mfd_add_devices with devm_mfd_add_devices to automatically
manage the device resources.
