[v6,0/4] add clock controller of qca8386/qca8084

qca8xxx is 4 * 2.5GBaseT ports chip, working as switch mode
named by qca8386, or working as PHY mode named by qca8084,
clock hardware reigster is accessed by MDIO bus.

This patch series add the clock controller of qca8363/qca8084,
and add the clock ops clk_branch2_prepare_ops to avoid spin lock
used during the clock operation of qca8k clock controller where
the sleep happens when accessing clock control register by MDIO
bus.

Changes in v2:
	* remove clock flag CLK_ENABLE_MUTEX_LOCK.
	* add clock ops clk_branch2_qca8k_ops.
	* improve yaml file for fixing dtschema warnings.
	* enable clock controller driver in defconfig.

Changes in v3:
	* rename clk_branch2_qca8k_ops to clk_branch2_mdio_ops.
	* fix review comments on yaml file.
	* use dev_err_probe on driver probe error.
	* only use the compatible "qcom,qca8084-nsscc".
	* remove enable clock controller driver patch.

Changes in v4:
	* add _qcom_cc_really_probe function.
	* commonizing the probe function.
	* remove flag CLK_IS_CRITICAL from clocks only needed
	to be enabled in switch device.
	* update device tree property reg to 0x10. 

Changes in v5:
	* commonize qcom_cc_really_probe.
	* add halt_check for the branch clocks.
	* fix the review comments on nsscc-qca8k.c. 

Changes in v6:
	* rename clk_branch2_mdio_ops to clk_branch2_prepare_ops.
