    kernel - Improve ACPI compatibility with older BIOSes
    
    * ACPI alignment field in ACPI resources can sometimes be 0, leading
      to passing 0 for 'align' to acpi_res_set_iorange() which panics the
      box with a division-by-zero fault.
    
    * Relax handling of this argument by setting it to 1 if it is found
      to be 0.
    
    * Fixes DFly panics with certain older BIOSes.
