arm: mx5: Avoid hardcoding memory sizes on M53EVK
The DRAM size can be easily detected at runtime on i.MX53. Implement such detection on M53EVK and adjust the rest of the macros accordingly to use the detected values. An important thing to note here is that we had to override the function for trimming the effective DRAM address, get_effective_memsize(). That is because the function uses CONFIG_MAX_MEM_MAPPED as the upper bound of the available DRAM and we don't have gd->bd->bi_dram[0].size set up at the time the function is called, thus we cannot put this into the macro CONFIG_MAX_MEM_MAPPED . Instead, we use custom override where we use the size of the first DRAM block which we just detected.
