In init_winctx_regs(), __pa() is called on winctx->rx_fifo and this
function is called to initialize registers for receive and fault
windows. But the real address is passed in winctx->rx_fifo for
receive windows and the virtual address for fault windows which
causes errors with DEBUG_VIRTUAL enabled. Fixes this issue by
assigning only real address to rx_fifo in vas_rx_win_attr struct
for both receive and fault windows.

Pull powerpc updates from Michael Ellerman:
- A big series refactoring parts of our KVM code, and converting some
to C.
- Support for ARCH_HAS_SET_MEMORY, and ARCH_HAS_STRICT_MODULE_RWX on
some CPUs.
- Support for the Microwatt soft-core.
- Optimisations to our interrupt return path on 64-bit.
- Support for userspace access to the NX GZIP accelerator on PowerVM on
Power10.
- Enable KUAP and KUEP by default on 32-bit Book3S CPUs.
- Other smaller features, fixes & cleanups.
