Looks good but there is an issue with this. The most important part of the code is to detect the SoC. Filling the name, technology, etc is easy, but the hard thing is to actually detect the SoC. To do so, cpufetch will look at /proc/cpuinfo and read the Hardware line, and will try to match it against the string that you use in match_xxx.
For example, let's look at the Pinephone, which has Allwinner A64 (see this link). The reported hardware in this case is sun50iw1p1 which could be shortened to sun50i. Following the URL that you posted we can build a function like yours and actually match the CPU against the sun50i string. But here is the thing. There are a lot of SoCs that can be matched with sun50i. In the webpage (see this table), if we use sun50iw1p1, it can be either A64, H64, or R18...
So it seems that it is impossible to unequivocally detect a Allwiner SoC by its name in /proc/cpuinfo

I wrote this but I'm not sure about the syntax, with: Name, Series, ENUM, soc, "technology"/"process" I only put SoC where the technology is known from the page in link. This is a wiki of people working on open source driver for AllWinner SoCs, mainly by reverse engineering.
