plat/arm/sgi: Use platform specific functions to get platform ids

Add two new functions 'plat_arm_sgi_get_platform_id' and
'plat_arm_sgi_get_config_id' which will be implemented by all the
SGI platforms. These functions can be used to determine the part
number and configuration id of the SGI platforms.

In BL2, these functions are used to populate the 'system-id' node.
In BL31, these functions are used to populate the 'sgi_plat_info_t'
structure with the part number and configuration id of the platform.
