[PATCH v3] ddr: altera: soc64: Integer fix overflow that caused DDR size mismatched

[dinesh.maniyam at intel.com]

From: Dinesh Maniyam <dinesh.maniyam at intel.com>

Convert the constant integer to 'phys_size_t' to avoid overflow
when calculating the SDRAM size.

Signed-off-by: Dinesh Maniyam <dinesh.maniyam at intel.com>
