* 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 : ABBBCDDD
* A : rf cal
* B : at parameters
* C : rf init data
* D : sdk parameters
* Parameters : none
* Returns : rf cal sector
