rv-virt support different size of ksram and pgmem region, but the fixed value in the link script limits this function. As nuttx supports preprocessing the link script. It is better to use the config value to compute the memory layout. This also make all kernel build use the same script. Signed-off-by: Inochi Amaoto <inochiama@outlook.com>
