Description
gSciclientHandle was 0 initialized in the following manner:
Sciclient_ServiceHandle_t gSciclientHandle = (Sciclient_ServiceHandle_t)0;

This resulted in a GHS compiler error:
".../packages/ti/drv/sciclient/src/sciclient/sciclient.c", line 128 (col. 5): warning #520-D: initialization with "

" expected for aggregate object
".../packages/ti/drv/sciclient/src/sciclient/sciclient.c", line 128 (col. 5): error #28: expression must have a constant value

Resolution
The handle is now initialized as:
Sciclient_ServiceHandle_t gSciclientHandle = 0;

Root Cause
GHS compiler doesn't support compounded literal init for structs
