  powerpc/xics: Set the IRQ chip data for the ICS native backend (2021-09-15 22:05:53 +1000)

- ------------------------------------------------------------------
powerpc fixes for 5.15 #2

Fix crashes when scv (System Call Vectored) is used to make a syscall when a transaction
is active, on Power9 or later.

Fix bad interactions between rfscv (Return-from scv) and Power9 fake-suspend mode.

Fix crashes when handling machine checks in LPARs using the Hash MMU.

Partly revert a recent change to our XICS interrupt controller code, which broke the
recently added Microwatt support.

Thanks to: Cédric Le Goater, Eirik Fuller, Ganesh Goudar, Gustavo Romero, Joel Stanley,
Nicholas Piggin.
