Power11 core is same as Power10, use the existing functionalities to
introduce a Power11 chip and machine, with Power10 chip as parent of
Power11 chip, thus going through similar class_init paths

This patch should come last, after all the POWER11 processor sub-unit
models (HOMER, OCC, LPC) are implemented. Also the POWER11 chip model
lacks an instance_init() handler initializing the chip children to the
correct POWER11 types.
AFAICT, power11-pnv-chip is still using power10 types.

I wonder if we should not duplicate the PNV10 macros in PNV11. It's minor.
