omap2420-h4: Fix DRAM initialisation
The size of the DRAM for the omap2420-h4 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 omap2420-h4 board and setup the DRAM size there. Signed-off-by: Jon Hunter <jon-hunter@ti.com>
