Add paths for Qualcomm firmware, including:
ipa, modem, bluetooth, venus, gpu

Enable adsp and cdsp nodes since their firmware is present

GPU and bluetooth are confirmed working, others may need more
testing/fixes

But regardless they will need the firmware paths specified here
and firmware added upstream before they will work, so might as well
get started on it now.

This commit message is a little out of sync with the patch content

You're changing all of these paths.. have the previous ones ever
been used, e.g. in pmOS, to the best of your knowledge?

The previous values have been used in pmos, but I can fix the firmware package when it comes time for pmos to sync this back.
