config STUB_CLK_HI6220
clk/driver/hisi: Consolidate the Kconfig for the CLOCK_STUB The current defconfig is inconsistent as it selects the mailbox and the clock for the hi6220 and the hi3660 without having their Kconfigs making sure the dependencies are correct. It ends up when selecting different versions for the kernel (for example when git bisecting) those options disappear and they don't get back, leading to unexpected behaviors. In our case, the cpufreq driver does no longer work because the clock fails to initialize due to the clock stub and the mailbox missing. In order to have the dependencies correctly set when defaulting, let's do the same as commit 3a49afb84ca074e ("clk: enable hi655x common clk automatically") where we select automatically the driver when the parent driver is selected.

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.
