[U-Boot] [PATCH v2 2/4] arm: imx: cx9020: move dram init into common place

[linux-kernel-dev at beckhoff.com]

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

Move dram_init(), dram_init_banksize() and get_effective_memsize() to
arch/arm/mach-imx/mx5/mx53_dram.c, where it can be reused by m53evk and
mx53loco.

Signed-off-by: Patrick Bruenn <p.bruenn at beckhoff.com>
