powerpc updates for 6.4

Browse source 
- Add support for building the kernel using PC-relative addressing on Power10.
 
  - Allow HV KVM guests on Power10 to use prefixed instructions.
 
  - Unify support for the P2020 CPU (85xx) into a single machine description.
 
  - Always build the 64-bit kernel with 128-bit long double.
 
  - Drop support for several obsolete 2000's era development boards as
    identified by Paul Gortmaker.
 
  - A series fixing VFIO on Power since some generic changes.
 
  - Various other small features and fixes.

* To enable external serial I/O on a Freescale MPC 8323 SYS/MDS board, do
* this:
*
* 1) On chip U61, lift (disconnect) pins 21 (TXD) and 22 (RXD) from the board.
* 2) Solder a wire from U61-21 to P19A-23. P19 is a grid of pins on the board
* next to the serial ports.
* 3) Solder a wire from U61-22 to P19K-22.
*
* Note that there's a typo in the schematic. The board labels the last column
* of pins "P19K", but in the schematic, that column is called "P19J". So if
