ath10k: Avoid override CE5 configuration for QCA99X0 chipsets
As the exisiting CE configurations are defined in global, there are the chances of QCA99X0 family chipsets CE configurations are getting changed by the ath10k_pci_override_ce_config() function. The override will be hit and CE5 configurations will be changed, when the user bring up the QCA99X0 chipsets along with QCA6174 or QCA9377 chipset. (Bring up QCA99X0 family chipsets after QCA6174 or QCA9377). Hence, fixing this issue by moving the global CE configuration to radio specific CE configuration. Tested hardware: QCA9888 & QCA6174 Tested firmware: 10.4-3.10-00047 & WLAN.RM.4.4.1.c3-00058 Signed-off-by: Maharaja Kennadyrajan <mkenna@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1587649759-14381-1-git-send-email-mkenna@codeaurora.org
