Subject: [PATCH 4/5] ath10k: set CTS protection VDEV param only if VDEV is up

The cts protection vdev parameter, in new QCA9377 TF2.0 firmware,
requires bss peer to be created for the STATION vdev type.
bss peer is being allocated by the firmware after vdev_start/_up commands.
mac80211 may call the cts protection setup at any time, so the
we needs to track the situation and defer the cts configuration
to prevent firmware asserts, like below:

Subject: [PATCH 3/5] ath10k: decrease num of peers support

The correct number for QCA9377 chip is 33 VDEVs.
This impacts also QCA6174 chip and it's max VDEV number.

Subject: [PATCH 2/5] ath10k: override CE5 config for QCA9377

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.
