powerpc: Add hardware description string
Create a hardware description string, which we will use to record
various details of the hardware platform we are running on.
Print the accumulated description at boot, and use it to set the generic
description which is printed in oopses.
To begin with add ppc_md.name, aka the "machine description".
Example output at boot with the full series applied:
Linux version 6.0.0-rc2-gcc-11.1.0-00199-g893f9007a5ce-dirty (michael@alpine1-p1) (powerpc64-linux-gcc (GCC) 11.1.0, GNU ld (GNU Binutils) 2.36.1) #844 SMP Thu Sep 29 22:29:53 AEST 2022
