ath10k: ath11k: add specific LinuxKPI support
Add files needed by ath1?k drivers to linuxkpi/linuxkpi_wlan.
This contain (skeleton) implementations of what is needed to
compile but specifically mhi/qmi/qrtr will need more work for
ath11k.
(cherry picked from commit 06a1103fe38677ba6213cae321255f53e9476dcd)
