Build the Hisilicon Hi6220 stub clock driver.
clk: hisilicon: Add support for Hi3660 stub clocks Hi3660 has four stub clocks, which are big and LITTLE cluster clocks, GPU clock and DDR clock. These clocks ask MCU for frequency scaling by sending message through mailbox. This commit adds support for stub clocks, it requests the dedicated mailbox channel at initialization; then later uses this channel to send message to MCU to execute frequency scaling. The four stub clocks share the same mailbox channel, but every stub clock has its own command id so MCU can distinguish the requirement coming for which clock. A shared memory is used to present effective frequency value, so the clock driver uses I/O mapping for the memory and reads back rate value.
