drivers/intel/fsp2_0: set BootLoaderTolumSize generically
The amount of reserved memory just below the DRAM limit in
32-bit space is defined in the FSP 2.0 specification within
the FSPM_ARCH_UPD structure. There's no need to make the
chipset code set the same value as needed for coreboot.
The chipset code can always change the value if it needs
after the common setting being applied.
Remove the call in soc/intel/apollolake as it's no longer
needed.
