arm: mediatek: mt8512: fix gd->bd->bi_dram[0].size

Browse Source 
Use board_get_usable_ram_top() instead of get_effective_memsize() to
limit gd->ram_top.

Both board_get_usable_ram_top() and get_effective_memsize() are used to
set gd->ram_top in setup_dest_addr(). However, get_effective_memsize()
also sets gd->bd->bi_dram[0].size in dram_init_banksize(), which is
undesirable.

Prior to commit b9e6281632 ("arm: mediatek: mt8512:
drop dram_init_banksize()"), gd->bd->bi_dram[0].size was overridden in
a board-specific dram_init_banksize() implementation.

We can just use board_get_usable_ram_top() now to set gd->ram_top to the
correct value instead. Overriding gd->bd->bi_dram[0].size was a bit
confusing since it isn't easily apparent which order the functions that
set it are called.
