  hw/ppc/e500: Implement pflash handling (2022-10-28 13:26:20 -0300)

----------------------------------------------------------------
ppc patch queue for 2022-10-28:

This queue has the second part of the ppc4xx_sdram cleanups, doorbell
instructions for POWER8 and new pflash handling for the e500 machine.

It also has a lot of performance optimizations in the PowerPC emulation
done by the researchers of the Eldorado institute. Between using gvec
for VMX/VSX instructions, a full rework of the interrupt model and PMU
optimizations, they managed to drastically speed up the emulation of
powernv8/9/10 machines.  Here's an example with avocado tests:

- with master:

tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (38.89 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (43.89 s)

- with this queue applied:

tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (21.23 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (22.58 s)

Other ppc machines, like pseries, also had a noticeable performance
boost.
