ath11k-firmware: update IPQ8074 and QCN9074 to 2.9.0.1-02146
After a long time QCA has pushed an updated release of 2.9.0.1 firmware
for IPQ8074 and QCN9074, so lets update to 2.9.0.1-02146.
Sadly, still nothing new for IPQ6018.
QCA has also moved the repository where they will be posting firmware to
their CodeLinaro instance, so we move to using that and it allows us to
remove the manual download of QCN9074 board-2.bin.
