bus: ti-sysc: AM3: RNG is GP only

commit a6d90e9f22328f07343e49e08a4ca483ae8e8abb upstream.

Make the RNG on AM3 GP only.

Based on this patch from TI v5.4 tree which is based on hwmod data
which are now removed:

| ARM: AM43xx: hwmod: Move RNG to a GP only links table
|
| On non-GP devices the RNG is controlled by the secure-side software,
| like in DRA7xx hwmod we should not control this IP when we are not
| a GP device.
