[U-Boot] [PATCH 4/6] arm: socfpga: arria10: don't build GEN5 sdram for arria10

[dinguyen at opensource.altera.com]

From: Dinh Nguyen <dinh.linux at gmail.com>

The Arria10 device will not be able to re-use the GEN5 SDRAM controller,
so we shouldn't build the driver. Move CONFIG_ALTERA_SDRAM to Kconfig
option in drivers/ddr/altera/Kconfig.
