Instead of adding missing definitions to the existing at91sam9_ddrsdr.h and adapting the incoming DDRAM initialization code from at91bootstrap, just replace the lightly used existing header with: https://github.com/linux4sam/at91bootstrap/blob/v3.8.12/include/arch/at91_ddrsdrc.h
For easier comprehension, the replacement is done in three steps: This last step copies the memory size querying functions from at91sam9_ddrsdr.h to at91_ddrsdrc.h, then deletes it and fixes all references.
