Subject: [PATCH 2/2] cpufreq: qcom-nvmem: add support for IPQ8074

IPQ8074 comes in 2 families:
* IPQ8070A/IPQ8071A (Acorn) up to 1.4GHz
* IPQ8072A/IPQ8074A/IPQ8076A/IPQ8078A (Hawkeye) up to 2.2GHz

So, in order to be able to share one OPP table lets add support for IPQ8074
family based of SMEM SoC ID-s as speedbin fuse is always 0 on IPQ8074.

IPQ8074 compatible is blacklisted from DT platdev as the cpufreq device
will get created by NVMEM CPUFreq driver.

I'd say pr_err, or at least WARN() + setting the slowest bin would be
more desirable here, cpufreq probes early so people without uart etc.
will be unlikely to find out why their kernel dies.
