powerpc/85xx: Add P2020DS board support
The P2020 is a dual e500v2 core based SOC with: * 3 PCIe controllers * 2 General purpose DMA controllers * 2 sRIO controllers * 3 eTSECS * USB 2.0 * SDHC * SPI, I2C, DUART * enhanced localbus * and optional Security (P2020E) security w/XOR acceleration The p2020 DS reference board is pretty similar to the existing MPC85xx DS boards and has a ULI 1575 connected on one of the PCIe controllers.
