arm, am335x: add support for 3 siemens boards
add support for the am335x based boards from siemens:
dxr2:
- DDR3 128MiB
- NAND 256MiB
- Ethernet with external Switch SMSC LAN9303
- no PMIC
- internal Watchdog
- DFU support
pxm2:
- DDR2 512 MiB
- NAND 1024 MiB
- PMIC
- PHY atheros ar803x
- USB Host
- internal Watchdog
- DFU support
rut:
- DDR3 256 MiB
- NAND 256 MiB
- PMIC
- PHY natsemi dp83630
- external Watchdog
- DFU support
