[PATCH 1/2] hw/loongarch/virt: Fix big endian support with MCFG table


From: Bibo Mao
Subject: [PATCH 1/2] hw/loongarch/virt: Fix big endian support with MCFG table
Date: Wed, 4 Jun 2025 14:55:01 +0800

With API build_mcfg(), it is not necessary with parameter structure
AcpiMcfgInfo to convert to little endian since it is directly used
with host native endian.

Here remove endian conversion before calling function build_mcfg().
With this patch, bios-tables-test passes to run on big endian host
machine S390.
