plat/arm/css/sgm: Reorder early platform init

In the function, bl1_early_platform_setup in the file
plat/arm/css/sgm/sgm_bl1_setup.c:

  plat_config_init();

  arm_bl1_early_platform_setup();

The debug messages logged by plat_config_init() are lost because
the console is initialized in the function
arm_bl1_early_platform_setup()

To see the logs of plat_config_init, this fix re-orders above calls
so that the console is initialized before call to plat_config_init.
