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.

pll_vco structure are never modified. They are used as .vco_table in
"struct clk_alpha_pll".
And in this structure, we have:
const struct pll_vco *vco_table;
Constifying these structures moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig:

The frequency table arrays are supposed to be terminated with an
empty element. Add such entry to the end of the arrays where it
is missing in order to avoid possible out-of-bound access when
the table is traversed by functions like qcom_find_freq() or
qcom_find_freq_floor().
Only compile tested.

Instead of magically poking at the bit0 of branch clocks' CBCR, use
the newly introduced helper.

If "regmap" is an error pointer then calling regmap_update_bits() will
crash. We only need to call regmap_update_bits() if we had written to
it earlier.

Add the sc8280xp CAMCC driver which follows the sdm845 CAMCC lineage
with additional CCI and IFE blocks and more granular clock parentage.
