New HAL includes some driver changes to register accesses.
Adds support for WLAN devices on AR5312 family devices.
Adds support 32-bit SPARC ath devices (untested).
ath enabled in SPARC64 GENERIC builds.
This HAL is tested and known to work for i386 PCI devices, SPARC64 PCI devices,
and AR5312 WiSoC devices. MIPS PCI devices appear to be busted (possibly only
on Alchemy hardware, unconfirmed), and cardbus support is untested due to
lack of test hardware.
Please report any new problems with this import to garrett@.
