With the current implementation of wmi init command,
there is no provision for the host driver to provide mem
chunks addresses with more than 32-bit, to the firmware.
WCN3990 is a 35-bit target and can accept mem chunks addresses
which are above 32-bit.

If firmware supports address range more than 32 bit, it
advertises the support by setting the WMI_SERVICE_EXTEND_ADDRESS
service. Based on this service fill the upper bits of paddr while
providing the mem chunks in the wmi init command.

Tested HW: WCN3990
Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1
