The four Cortex-A76 CPU cores on R-Car V4M share their Operating
Performance Points (OPP) table, but they have independent clocks.
All cores in the cluster can switch DVFS states independently, hence
the cluster's OPP table should not have an "opp-shared" property.

Before, only a single CPU frequency policy is created:
cpufreq: cpufreq_online: CPU0: Running at unlisted initial frequency: 999999 KHz, changing to: 1000000 KHz
/sys/devices/system/cpu/cpu0/cpufreq -> ../cpufreq/policy0
/sys/devices/system/cpu/cpu1/cpufreq -> ../cpufreq/policy0
/sys/devices/system/cpu/cpu2/cpufreq -> ../cpufreq/policy0
/sys/devices/system/cpu/cpu3/cpufreq -> ../cpufreq/policy0
After, four independent CPU frequency policies are created:
cpufreq: cpufreq_online: CPU0: Running at unlisted initial frequency: 999999 KHz, changing to: 1000000 KHz
cpufreq: cpufreq_online: CPU1: Running at unlisted initial frequency: 999999 KHz, changing to: 1000000 KHz
cpufreq: cpufreq_online: CPU2: Running at unlisted initial frequency: 999999 KHz, changing to: 1000000 KHz
cpufreq: cpufreq_online: CPU3: Running at unlisted initial frequency: 999999 KHz, changing to: 1000000 KHz
/sys/devices/system/cpu/cpu0/cpufreq -> ../cpufreq/policy0
/sys/devices/system/cpu/cpu1/cpufreq -> ../cpufreq/policy1
/sys/devices/system/cpu/cpu2/cpufreq -> ../cpufreq/policy2
/sys/devices/system/cpu/cpu3/cpufreq -> ../cpufreq/policy3
To be queued in renesas-devel for v6.11.
