The firmware path for the sm8250 resources is incorrect. This fixes the

Is the policy not to stick with .mdt for existing platforms but use .mbn
for new platforms.
This was slightly different for venus, where it was suggested to use
.mdt for all the platforms. However last year when Chrome team was
updating sc7280/sc7180 Venus firmware, Rob Clark and yours truly have
persuaded them to (finally) switch to .mbn and provide compatibility
.mdt symlinks.
Then we have similarly converted all the rest of the venus firmware files.

Its a symlink for me but, is it a symlink for everybody ?
root@linaro-gnome:~# ls /lib/firmware/qcom/vpu-1.0/ -l
lrwxrwxrwx 1 root root 9 Dec 2 2022 venus.mdt -> venus.mbn
Yes, it is a symlink for everybody:
$ grep Link.*qcom.v linux-firmware/WHENCE
Link: qcom/venus-1.8/venus.mdt -> venus.mbn
Link: qcom/venus-4.2/venus.mdt -> venus.mbn
Link: qcom/venus-5.2/venus.mdt -> venus.mbn
Link: qcom/venus-5.4/venus.mdt -> venus.mbn
Link: qcom/vpu-1.0/venus.mdt -> venus.mbn
So, long story short, I think this patch makes sense (and we should
update other entries in this file too).
Patrick, maybe you can do it as well?
