alsa-info: add ACPI device status
BIOS vendors typically reuse the same definitions between different
platforms and expose the relevant hardware by changing the value of
the _STA method.
For example on the Asus T100HA, there are 3 HID values for audio
codecs in the DSDT table but two have a zero status and will be
ignored by the ACPI subsystem.
$ more /sys/bus/acpi/devices/10EC*/status
::::::::::::::
/sys/bus/acpi/devices/10EC3270:00/status
::::::::::::::
15
::::::::::::::
/sys/bus/acpi/devices/10EC5640:00/status
::::::::::::::

/sys/bus/acpi/devices/10EC5648:00/status

This information is very useful to figure out which HIDs/quirks need
to be supported. Add log to alsa-info.sh to only expose non-zero
results of the ACPI _STA method, e.g.
!!ACPI Device Status Information
!!---------------
/sys/bus/acpi/devices/10EC3270:00/status 15
