From: Bibo Mao <maob...@loongson.cn>
Loongson IPI is only available in little-endian,
so use that to access the guest memory (in case
we run on a big-endian host).
Signed-off-by: Bibo Mao <maob...@loongson.cn>
Fixes: f6783e3438 ("hw/loongarch: Add LoongArch ipi interrupt support")
[PMD: Extracted from bigger commit, added commit description]
