Most likely because of the TZ differences, on QCM6490 / QCS6490 boards
the WPSS DSP can not work with the existing firmware (provided for
SC7280 platforms). Add device-specific firmware for these boards.
The firmware comes in the MBN format rather than the typical MDT + Bnn
as the firmware file is being loaded through the remoteproc / DSP.
Compatibility links are added to follow the names in the existing DTs
(qcom/qcm6490-idp.dts and qcom/qcs6490-rb3gen2.dts).

As demonstrated by the inability to use existing WCN6750 firmware on
QCM6490 / QCS6490 devices, such firmware files are device-specific. As a
preparation to adding more device-specific firmware, move existing
firmware to the sc7280/ subdir, squashing it in proceess. Squashing it
simplifies loading (as it requires just a single file access / userspace
call) and also it requires just a single compatibility symlink instead
of ten.
