As part of the integration of the new ML package, also update the
ethos-u-firmware binary built from Stash:
Repo: emp/ethos_u_firmware.git
Revision: a0352b0cf7267c896b55980dedd08daddc780733
Source: NXP's MCUXpresso SDK_2.14.0_MIMX9352xxxxK
And, drop deepview-rt support for ccimx93, as NXP has done the same in
6.1.36-2.1.0 release.
