Log Message:
emuxki(4): restrict DMA memory within the first 2GB

As implemented in the driver, the EMU10K1 chip can only address memory
up to 31-bit addresses.

Tested on NetBSD/amd64 with a Sound Blaster Live! Value (CT4870, PCI)
and with a Sound Blaster Audigy Rx 7.1 (SB1550, PCIe).

Additional sound cards sponsored by the NetBSD Foundation; thanks!
