brcm2708: make it boot on revision 2 raspberry pis
* update the bootcode.bin to the newest version
- gpu/cpu mem split is now configured through config.txt, so no need
to create more than one sd card image (just edit the config.txt)
- bootcode.bin now supports the never revision 2 raspberry pis
* add a commented prepopulated config.txt for easier config changes

## Details taken from the eLinux wiki
|

## Description:
|
||||
## Details of each setting are described with each section that begins with
|
||||
## a double hashed comment ('##')
|
||||
## It is up to the user to remove the single hashed comment ('#') from each
|
||||
## option they want to enable, and to set the specific value of that option.
|
||||
##
|
||||
## WARNING: Setting the following combination of parameters will set a
|
||||
## permanent bit within the SOC and your warranty is void.
|
||||
## over_voltage>0, and at least one of the following:
|
||||
## force_turbo=1
|
||||
## current_limit_override=0x5A000020
|
||||
## temp_limit>85
|
||||
##
|
||||
## Overclock settings will be disabled at runtime if the SoC reaches temp_limit
