powerpc/8xx: Add DT node for using the SEC engine of the MPC885
The MPC885 has SEC engine version 1.2 with the following details:
- Number of Crypto channels: 1
- Exec Units: DEU, MDEU and AESU
- Available descriptors: 00010, 00100, 00110, 01000, 11000, 11010
It is also supposed to have descriptor 00000, but it doesn't work
properly so we keep it out for the moment.
