LoongArch: Align ACPI structures if ARCH_STRICT_ALIGN enabled
ARCH_STRICT_ALIGN is used for hardware without UAL, now it only control
the -mstrict-align flag. However, ACPI structures are packed by default
so will cause unaligned accesses.
To avoid this, define ACPI_MISALIGNMENT_NOT_SUPPORTED in asm/acenv.h to
align ACPI structures if ARCH_STRICT_ALIGN enabled.
