updates for the siemens am335x based boards:

- draco: add delay for DDR3 configuration - change MTD partition layout and add a possibility to redefine MTD layout in board header. - move ubi support to common header file - draco: improve dtb naming - draco: set CONFIG_SYS_CBSIZE to 1024 - add generic env based led Leds can now be defined in Environment - add generic env based dfu button Which gpio is used for the dfu button can be defined through the Environment - set MACH_TYPE only if defined - draco: increase CPU freq to 300MHz - Add time command to siemens am33xx boards - DDR3: increase default tRFC - draco: enable pullup for DFU and ERST pin - change print format DDR3
