ARM: tegra: derive CONFIG_SPL_MAX_SIZE instead of hard-coding it 

For Tegra, the SPL and main U-Boot are concatenated together to form a
single memory image. Hence, the maximum SPL size is the different in
TEXT_BASE for SPL and main U-Boot. Instead of manually calculating
SPL_MAX_SIZE based on those two TEXT_BASE, which can lead to errors if
one TEXT_BASE is changed without updating SPL_MAX_SIZE, simply perform
the calculation automatically.
