wifi: ath12k: read single_chip_mlo_support parameter from QMI PHY capability

New parameter 'single_chip_mlo_support' was added in QMI PHY
capability response message. This is an optional parameter added
in QCN9274 firmware. This parameter states if the firmware
supports Single-Link Operation (SLO) and Multi-Link Operation (MLO)
within the same device.

If single_chip_mlo_support = 1, then intra device SLO/MLO is supported
in the firmware.
If single_chip_mlo_support = 0, then intra device SLO/MLO is not
supported in the firmware.

Hence, add support to read 'single_chip_mlo_support' parameter from
the QMI PHY capability response message.
