Fix OpenSBI configuration for newer versions
...
OpenSBI 1.3 an newer require the heap_size to be specified in the
sbi_platform structure, othewise the default 0 value causes a hangg at
the start. I found the problem after bisecting OpenSBI:
# Bisect opensbi
version = src.shortRev;
src = builtins.fetchGit {
url = "file:///home/Computational/rarias/riscv/opensbi";
#rev = "908be1b85c8ff0695ea226fbbf0ff24a779cdece"; #good
