[PATCH] wifi: ath10k: add chain mask and spatial stream params for qca988x

[Ramakrishnan Rathinasamy]

For QCA988x, the tx_chain_mask, rx_chain_mask, and max_spatial_stream
hardware parameters are not initialized when using the 10.4 firmware.
However, the hardware announces its max_spatial_stream capabilities
during the WMI ready event. The driver compares this against the
uninitialized (zero) value, which triggers the following warning:

"hardware advertises support for more spatial streams than it should (3 > 0)"

Consequently, the driver's max_spatial_stream evaluates to zero. This
prevents the device from associating with modern Access Points in
station mode, causing the AP to reject the association with reason
code 18 (Association denied).

Fix this issue by properly populating the tx_chain_mask, rx_chain_mask,
and max_spatial_stream hardware parameters for QCA988x.
