Add qcom_cpufreq_match_data for IPQ9574. This is used for tying
up the cpu@N nodes with the power domains. match_data_kryo is not
used since it doesn't set genpd_names. If genpd_names is not set,
'cat /sys/kernel/debug/qcom_cpr3/thread0' causes cpr3_debug_info_show()
to crash while trying to read thread->corner->last_uV as
thread->corner is NULL.
Call trace:
cpr3_debug_info_show
