qcacmn: Disable MSI intr config for CE5 on Lithium targets

FW is not setting up any context for CE5 but host is still
configuring the dest and status ring for CE5. This can
result in CE5 HW to write to MSI iova address when PCIe is
in low power state.

Fix is to disable MSI intr configuration for CE5 on
Lithium based targets.
