cnss: Provide API to CLD Driver to control SPDT GPIO

Browse source 
Antenna Sharing GPIO need to be toggled between QCA PCIe and SDIO
devices based on the requirement. If SDIO device is to be operational,
this GPIO should be turned ON high.

Expose API to CLD Driver to control this GPIO for dual-wifi platforms.
