Added ability to set bus type and configure the max number of peers in the ath10k_hw_params struct. With this functionality it is possible to have a different hw configuration depending on bus type for the same radio chipset. E.g. SDIO and USB devices using the same chipset as PCIe devices will potentially use different board files and perhaps other configuration parameters. One such parameter is the max number of peers. Instead of using a default value (suitable for PCIe devices) derived from the WMI op version, a per target value can be used instead. This is needed by the QCA9377 USB device in order to prevent the target fw to crash after HTT RX ring cfg is issued. Apparently, the QCA9377 HL device does not seem to handle the same amount of peers as the LL devices. A new struct ath10k_hw_params item for QCA9377 USB devices was also added to ath10k_hw_params_list.
