ebec04773b clk: qcom: spmi-pmic-div: convert from round_rate() to determine_rate() 
The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
on the cover letter of this series.

a5be6db5a2 clk: qcom: clk-spmi-pmic-div: Annotate struct spmi_pmic_div_clk_cc with __counted_by 
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct spmi_pmic_div_clk_cc.

a622c1dc84 clk: qcom: clk-spmi-pmic-div: convert to use parent_data 
The clk-spmi-pmic-div driver gets the parent name from the first (and
the only) clock parent. So, use parent data, index 0 to setup the clock.

4cfaa55f42 clk: qcom: Add spmi_pmic clock divider support 
Clkdiv module provides a clock output on the PMIC with CXO as
the source. This clock can be routed through PMIC GPIOs. Add
a device driver to configure this clkdiv module.
