[PATCH v3 4/5] clk: Hi6220: add stub clock driver

On Hi6220, there have some clocks which can use mailbox channel to send messages to power controller to change frequency; this includes CPU, GPU and DDR clocks. For dynamic frequency scaling, firstly need write the frequency value to SRAM region, and then send message to mailbox to trigger power
