>Description:
snd_hda(4) fails to attah on recent -current, while it was working on releng6.

The device is a onboard audio on Asus p5b deluxe bobo (intel chipset)
pcm0 at pci0:27:0: class=0x040300 card=0x81ec1043 chip=0x284b8086
rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82801H (ICH8 Family) HD Audio Controller'
    class      = multimedia


As discussed with ariff@ on #freebsd-azalia, this doesn't seems to be snd_hda problem(i've tried numerous revisions of snd_hda with no luck), but rather something other changed in -current.

>How-To-Repeat:
kldload snd_hda

pcm0: <Intel 82801H High Definition Audio Controller> mem
0xfebfc000-0xfebfffff irq 22 at device 27.0 on pci0
pcm0: hdac_mem_alloc: Unable to allocate memory resource
device_attach: pcm0 attach returned 6

It fails on bus_alloc_resource_any() in hdac_mem_alloc().
