fsp_broadwell_de: Switch CPU to high frequency mode
According to Yang York the FSP is responsible for switching the CPU into high frequency mode (HFM). For an unknown reason this is not done for the BSP on my platform though the APs are switched properly. This code switches the CPU into HFM which makes sure that all cores are in high frequency mode before payload is started. It should not harm the operation even if FSP was successful in switching to HFM.
