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.

Changes in v4:
* Add support for IPQ8174 (Oak) family

Changes in v3:
* Use enum for SoC versions

Changes in v2:
* Print an error if SMEM ID is not part of the IPQ8074 family
and restrict the speed to Acorn variant (1.4GHz)

Generally this lands in a separate commit, but I guess since Viresh takes changes to both of the files, it's even better..
