ACPI: Implement proper length checks for mem resources

Check whether the resulting length is the same as the given
length. Check for start <= end as well.

We need to hand in the resource for this, so we can apply the flags
directly.

[Jiang] Remove enforcement that resource starting address must be
non-zero.
