[U-Boot] [PATCH v3 3/4] arm: imx: m53evk: remove usage of mx53_dram_size

From: Patrick Bruenn <p.bruenn at beckhoff.com>
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 at beckhoff.com>

Changes in v3: None
Changes in v2: None
Only compile tested with make m53evk_defconfig
