Move dram_init_banksize() to a common header

Browse source 
This is an weak function present on all archs so we should have it in the
common header file. Remove it from arch-specific headers and add a
function comment.

/**
* dram_init_banksize() - Set up DRAM bank sizes
*
* This can be implemented by boards to set up the DRAM bank information in
* gd->bd->bi_dram(). It is called just before relocation, after dram_init()
* is called.
*
* If this is not provided, a default implementation will try to set up a
* single bank. It will do this if CONFIG_NR_DRAM_BANKS and
* CONFIG_SYS_SDRAM_BASE are set. The bank will have a start address of
* CONFIG_SYS_SDRAM_BASE and the size will be determined by a call to
* get_effective_memsize().
*
* @return 0 if OK, -ve on error
