Subject: [PATCH 4.9 37/41] ath10k: override CE5 config for QCA9377

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bartosz Markowski <bartosz.markowski@...to.com>

commit b08b5b53a1ed2bd7a883f8fd29232c8f03604671 upstream.

Similarly to QCA6174, QCA9377 requires the CE5 configuration to be
available for other feature. Use the ath10k_pci_override_ce_config()
for it as well.

This is required for TF2.0 firmware. Previous FW revisions were
working fine without this patch.
