ARM: at91: lds: add test for SPL binary size and bss size

Browse Source 
Add test for the SPL binary size and the bss section size.
This will throw an error at build time if the SPL sections
do not fit in the designated RAM area, thus avoiding oversizing the SPL.

Based on original work by Wenyou Yang.
