Cover letter [PATCH v6 0/2] Enable cpufreq for IPQ5332 & IPQ9574

This patch series aims to enable cpufreq for IPQ5332 and IPQ9574. For IPQ5332, a minor enhancement to Stromer Plus ops and a safe source switch is needed before cpu freq can be enabled.

These are also included in this series. Posting this as a single series. Please let me know if this is not correct, will split in the subsequent revisions.

Passed the following DT related validations
make W=1 ARCH=arm64 -j16 DT_CHECKER_FLAGS='-v -m' dt_binding_check DT_SCHEMA_FILES=qcom make W=1 ARCH=arm64 -j16 CHECK_DTBS=y DT_SCHEMA_FILES=qcom dtbs_check

For IPQ5332:
~~~~~~~~~~~
* This patch series introduces stromer plus ops which builds on stromer ops and implements a different set_rate and determine_rate.

A different set_rate is needed since stromer plus PLLs do not support dynamic frequency scaling. To switch between frequencies, we have to shut down the PLL, configure the L and ALPHA values and turn on again. So introduce the separate set of ops for Stromer Plus PLL.

* Update ipq_pll_stromer_plus to use clk_alpha_pll_stromer_plus_ops instead of clk_alpha_pll_stromer_ops.

* Set 'l' value to a value that is supported on all SKUs.

* Provide safe source switch for a53pll

* Include IPQ5332 in cpufreq nvmem framework

* Add OPP details to device tree

For IPQ9574:
~~~~~~~~~~~
* Include IPQ9574 in cpufreq nvmem framework

* Add OPP details to device tree
