[PATCH v5 02/19] hw/intc/loongson_ipi: Access memory in little endian

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

From: Bibo Mao <maobibo@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).

Fixes: f6783e3438 ("hw/loongarch: Add LoongArch ipi interrupt support")
[PMD: Extracted from bigger commit, added commit description]
