Fixed configuration for DDR Size discovered by Coreboot
For qemu-riscv value was incorrect. It was set to 32768 which
in turn was being used as 32768MB (32+GB), instead of the 32MB
it was intended to represent.
Change value so it is a select option based on in menuconfig
based on what you want coreboot to "discover" on boot.
Current three options are :
128MB
256MB
512MB
NOTE: You must specify greater than what is chosen from
the above items on the qemu cmdline.
