arm: imx: m53evk: remove usage of mx53_dram_size
Static variables are not available during board_init_f(). 'static uint32_t mx53_dram_size[2];' was used in board specific dram_init(), dram_init_banksize() and get_effective_memsize() to avoid multiple calls to get_ram_size(). Reused dram initialization functions from arch/arm/mach-imx/mx5/mx53_dram.c Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com>
