iommu/vt-d: Make DMAR_UNITS_SUPPORTED default 1024
If the available hardware exceeds DMAR_UNITS_SUPPORTED (previously set
to MAX_IO_APICS, or 128), it causes these messages: "DMAR: Failed to
allocate seq_id", "DMAR: Parse DMAR table failure.", and "x2apic: IRQ
remapping doesn't support X2APIC mode x2apic disabled"; and the system
fails to boot properly.
To support up to 64 sockets with 10 DMAR units each (640), make the
value of DMAR_UNITS_SUPPORTED default 1024.
