Different platforms have different DMA capability, on most of platforms, DMA support cache snooping. But few platforms, such as ElkhartLake (EHL), don't support cache snooping which requires cache flush from driver. So add a hardware level callback to let ishtp driver know if cache flush is needed. As most of platform support cache snooping, so driver will not do cache flush by default, until platform implements this callback and return true explicitly.
