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.
|

If this is merged, it should be flagged for stable v5.10+.
