[U-Boot] [PATCH] Kirkwood: bugfix: DRAM size initialization

[Tanmay Upadhyay]

If start of any DRAM bank is greater than total DDR size, remaining
DDR bank sizes were left un-initialized in dram_init function. This
could break other functions who uses array 'gd->bd->bi_dram'.Kirkwood
network driver is one example.
