This adds support for the Freescale COM Express P2020 board. This board is similar to the P1_P2_RDB, but has some extra (as well as missing) peripherals.

Unlike all other mpc85xx boards, it uses a watchdog timeout to reset. Using the HRESET_REQ register does not work.

This board has no NOR flash, and can only be booted via SD or SPI. This procedure is documented in Freescale Document Number AN3659 "Booting from On-Chip RAM (eSDHC or eSPI)." Some alternative documentation is provided in Freescale Document Number P2020RM "P2020 QorIQ Integrated Processor Reference Manual" (section 4.5).

Changes v1 -> v2: - fix checkpatch warnings - remove all references to NAND - update to top of tree U-Boot - remove CCSR relocation (top of tree code doesn't work)

I wish I could debug the CCSR relocation issue on this board, but I don't have a JTAG setup which is capable of debugging this issue.
