qualcommax: add ipq60xx support
Browse files Browse the repository at this point in the history 
Introduce support for the Qualcomm IPQ60xx SoC. WiFi support still has
to be handled and correctly fix hence this is currently marked as
source-only to have a solid base to progress on correct support of this
and hope Upstream QUIC publish newers ath11k drivers for this SoC.
