onenand|ddr: Add support for M39B0Rx0xxN1 Numonyx POP device

The M39B0Rx0xxN1 combines the following memory devices in MCP (multichip package):
  * 2-Gbit (x16), 1.8 V OneNANDTM flash memory, the NAND02GR4E0A
  * 4-Gbit DDP (DUAL DIE PLAN) (x16), 1.8 V OneNANDTM flash memory, the
    NAND04GR4E1A
  * Two or one single die of 2-Gbit double data rate LPSDRAM (low-power SDRAM), the
    M65KD002AM.

The datasheets are available from your local Numonyx distributor.
