Modify the rbspi_platform_setup() function to return the pointer of the
rb_info structure. This allows board specific setup routines to access
the various fields of the information. It is useful for investigating
the hardware option bits for example.
Also update the board setup codes, to ensure that those handle the new
return value correctly.
