st-info --chipid and --descr like functionality

[eugene-bright]

st-info can rougtly identify the chip:

$ st-info --chipid 
0x0466

$ st-info --descr
G030/G031/G041

I wonder if such functionality can be added to the pyOCD.

It looks like the chipid is stored in magic register 0xE000ED00 in case of STM32 chips https://github.com/stlink-org/stlink/blob/924e1ec93b9080593a10c02c25e483a0ceb60a04/src/common.c#L187 https://github.com/stlink-org/stlink/blob/cb551d50f879ec21e3d54c75041bffe506e830e5/doc/dev/developer.txt#L333

pyOCD's 'User script' feature is very handy to do things like this.

And also there is a valuable accumulation of knowledge in pystlink's repo nicely licensed under MIT license. https://github.com/pavelrevak/pystlink/blob/master/lib/stm32devices.py
