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.
