a8e4ab5bde clk: qcom: videocc: Constify 'struct qcom_cc_desc'
'struct qcom_cc_desc' is passed to qcom_cc_map() and
qcom_cc_really_probe() only as pointer to const, so make the memory
const for safety.

f903663a8d clk: qcom: videocc-sm8350: use HW_CTRL_TRIGGER for vcodec GDSCs
A recent change in the venus driver results in a stuck clock on the
Lenovo ThinkPad X13s, for example, when streaming video in firefox:

	video_cc_mvs0_clk status stuck at 'off'
	WARNING: CPU: 6 PID: 2885 at drivers/clk/qcom/clk-branch.c:87 clk_branch_wait+0x144/0x15c

using the out-of-tree sm8350/sc8280xp venus support. [1]

Update also the sm8350/sc8280xp GDSC definitions so that the hw control
mode can be changed at runtime as the venus driver now requires.

9f93a0a428 clk: qcom: common: commonize qcom_cc_really_probe
The previous wrapper qcom_cc_really_probe takes the platform
device as parameter, which is limited to platform driver.

As for qca8k clock controller driver, which is registered as
the MDIO device, which also follows the qcom clock framework.

To commonize qcom_cc_really_probe, updating it to take the
struct device as parameter, so that the qcom_cc_really_probe
can be utilized by the previous platform device and the new
added MDIO device.

Also update the current clock controller drivers to take
&pdev->dev as parameter when calling qcom_cc_really_probe.

d09ec6f987 clk: qcom: Use qcom_branch_set_clk_en()
Instead of magically poking at the bit0 of branch clocks' CBCR, use
the newly introduced helper.

bdc8fc1ecc clk: qcom: videocc-sm8350: Set delay for Venus CLK resets
Some Venus resets may require more time when toggling. Describe that.

The value is known for SM8350, see [1].

e5e527d1ed clk: qcom: videocc-sm8350: Add SC8280XP support
SC8280XP, being a partial derivative of SM8350, shares almost the exact
same videocc block. Extend the 8350 driver to support the bigger brother.

The only notable changes are higher possible frequencies on some clocks
and some switcheroo within the XO/sleep registers (probably due to some
different board crystal configuration).
