[U-Boot] [PATCH 07/19] arm: socfpga: Add DRAM bank size initialization function

[tien.fong.chee at intel.com]

From: Tien Fong Chee <tien.fong.chee at intel.com>

Add function for both multiple DRAM bank and single DRAM bank size
initialization. This common functionality could be used by every single
SOCFPGA board.
