[Bionic][PATCH 07/18] powerpc/powernv: Use __raw_[rm_]writeq_be() in pci-ioda.c

[Jose Ricardo Ziviani]

From: Michael Ellerman <mpe at ellerman.id.au>

BugLink: https://bugs.launchpad.net/qemu-kvm/+bug/1800649

This allows us to squash some sparse warnings and also avoids having
to do explicity endian conversions in the code.
