Makes iteration quicker.

0c4311e15c Remap interrupts to avoid 0 and duplicates
Let see if we can guess which is the correct number for the interrupts.
The plic should appear in the IRQ list but currently it doesn't.

30703d1715 Use the ttyS0 device for the console
For now it seems to be outputting the log properly, but it doesn't read

a40414d08c Add comment about the axi timer
This timer is present and initialized in OpenSBI and seems to drive the
UART device. Not sure if we need to see it from the kernel.

65c7eca2c8 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";
