This is a followup to the discussion during the Linaro Connect. Remove
most of the firmware-name properties from the board DT by using
root node compatible to detect firmware path.

The most obvious change is that the drivers now have to look for the
MBN firmware files by default, so this might break the case of the user
simply mounting vendor's firmware partition to /lib/firmware and
expecting it to work.

Also things are slightly more complex for the platforms like DB845c and
Qualcomm RB5. These platforms have generic SoC firmware in qcom/sdm845
and qcom/sm8250 and also the board-specific firmware at
qcom/sdm845/Thundercomm/DB845C and qcom/sm8250/Thundercomm/RB5
respectively. Making these boards follow up the scheme would require
additional symlinks in the firmware dir.
