acpi: fix incorrect encoding for 0x{F-1}FFFF
Fix typo in build_append_int() which causes integer
truncation when it's in range 0x{F-1}FFFF by packing it
as WordConst instead of required DWordConst.
In partucular this fixes a regression: hotplug in slots 16,17,18 and 19
didn't work, since SSDT had code like this:
If (And (Arg0, 0x0000))
{
Notify (S80, Arg1)
}
