cpufreq: qcom-nvmem: add support for IPQ8064

IPQ8064 comes in 3 families:
* IPQ8062 up to 1.0GHz
* IPQ8064/IPQ8066/IPQ8068 up to 1.4GHz
* IPQ8065/IPQ8069 up to 1.7Ghz

So, in order to be able to support one OPP table, add support for
IPQ8064 family based of SMEM SoC ID-s and correctly set the version so
opp-supported-hw can be correctly used.

Bit are set with the following logic:
* IPQ8062 BIT 0
* IPQ8064/IPQ8066/IPQ8068 BIT 1
* IPQ8065/IPQ8069 BIT 2

speed is never fused, only pvs values are fused.

IPQ806x SoC doesn't have pvs_version so we drop and we use the new
pattern:
opp-microvolt-speed0-pvs<PSV_VALUE>

Example:
- for ipq8062 psv2
  opp-microvolt-speed0-pvs2 = < 925000 878750 971250>
