pmdomain: core: add dummy release function to genpd device

Browse Source 
commit f64f610ec6 upstream.

The genpd device, which is really only used as a handle to lookup
OPP, but not even registered to the device core otherwise and thus
lifetime linked to the genpd struct it is contained in, is missing
a release function. After b8f7bbd1f4 ("pmdomain: core: Add
missing put_device()") the device will be cleaned up going through
the driver core device_release() function, which will warn when no
release callback is present for the device. Add a dummy release
function to shut up the warning.
