omap5912-osk: Fix DRAM initialisation

The size of the DRAM for the omap5912-osk board is getting setup in the
dram_init() function. However, for the current u-boot release this is
too late and needs to be done in dram_init_banksize(). Therefore, add
a dram_init_banksize() function for the omap5912-osk board and setup the
DRAM size there.
