Make the Linux kernel & Fiwix->Linux kexec more bare-metal-friendly

Browse source 
* Enable additional hardware drivers in Linux for better bare metal
  display, network & input device compatibility
* Disable ATA-over-Ethernet support, because it spams the network
  with unnecessary packets, is basically useless for bootstrapping,
  and may even be a security risk
* Increase Fiwix initrd size to 1280MB to fit a larger Linux build
* Make the Fiwix kexec size configurable the same way as initrd
  (and reduce from 280MB to 256MB which is sufficient in my testing)
* Use a more conservative memory map for Fiwix & Linux
* Boot Linux with consoleblank=0 on bare metal, so the build won't
  go blind after 5 minutes
* Support kexec-fiwix with interrupts disabled (will be useful later
  when builder-hex0 is updated)
