lets hold off on removing the /HAL/ support just right now. If we start stripping this stuff out then i'll make it harder to sync this code up with what I'm slowly hacking up in netbsd...

Bah, even more AH_SUPPORT_AR9130 code to be removed from the FreeBSD HAL.

The removed AH_SUPPORT_x has some counterparts in the FreeBSD HAL which this version now also removes.

Thanks!

QCA9565 in ath_hal.4 restored

Well, the bus abstraction as such deliberately is left in place, build-wise the PCI bus front-end just is coupled with the core support again (but as for the kernel, also only if has PCI support in the first place as usual). Generally, we consider PCI default enough that there are no seperate modules and devices for PCI bus front-ends even if support for additional busses exists. Currently, ath(4) and ath_pci(4) respectively are one of the very few odd ones out in this regard (I think virtio_pci(4) is the only other offender). Also, with all support for the very resource constraint platforms already gone, even if code for said USB chips would be added today, I believe the few bytes for the bus glue won't matter. The ARMv7 if_ath_pci.o currently is 25 KB and ARMv6 support also already on its way out ...

This change doesn't acutally fix white space violations but introduces additional ones as according to style(9): 'Second level indents are four spaces'.
