net: cnss: add DFS NOL support for dual WiFi

Store WiFi DFS NOL list and return to wlan host driver
on query. It adds support for no link operation on radar
detection.

This export symbol supported by both SDIO and PCIe platform
driver. So add this API as a common API for both SDIO and PCIe
interface based wlan module and remove the duplicate API from
the SDIO and PCIe platform driver.
