arm, am33xx: update for siemens am335x based boards
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
