* FunctionName : user_rf_cal_sector_set
* Description  : SDK just reversed 4 sectors, used for rf init data and paramters.
*                We add this function to force users to set rf cal sector, since
*                we don't know which sector is free in user's application.
*                sector map for last several sectors : ABCCC
*                A : rf cal
*                B : rf init data
*                C : sdk parameters
* Parameters   : none
* Returns      : rf cal sector
